SVN rev 227070 on 2011-11-04 04:02:50Z by jhb Add the posix_fadvise(2) system call. It is somewhat similar to madvise(2) except that it operates on a file descriptor instead of a memory region. It is currently only supported on regular files. Just as with madvise(2), the advice given to posix_fadvise(2) can be divided into two types. The first type provide hints about data access patterns and are used in the file read and write routines to modify the I/O flags passed down to VOP_READ() and VOP_WRITE(). These modes are thus filesystem independent. Note that to ease implementation (and since this API is only advisory anyway), only a single non-normal range is allowed per file descriptor. The second type of hints are used to hint to the OS that data will or will not be used. These hints are implemented via a new VOP_ADVISE(). A default implementation is provided which does nothing for the WILLNEED request and attempts to move any clean pages to the cache page queue for the DONTNEED request. This latter case required two other changes. First, a new V_CLEANONLY flag was added to vinvalbuf(). This requests vinvalbuf() to only flush clean buffers for the vnode from the buffer cache and to not remove any backing pages from the vnode. This is used to ensure clean pages are not wired into the buffer cache before attempting to move them to the cache page queue. The second change adds a new vm_object_page_cache() method. This method is somewhat similar to vm_object_page_remove() except that instead of freeing each page in the specified range, it attempts to move clean pages to the cache queue if possible. To preserve the ABI of struct file, the f_cdevpriv pointer is now reused in a union to point to the currently active advice region if one is present for regular files.

SVN rev 225617 on 2011-09-16 13:58:51Z by kmacy In order to maximize the re-usability of kernel code in user space this patch modifies makesyscalls.sh to prefix all of the non-compatibility calls (e.g. not linux_, freebsd32_) with sys_ and updates the kernel entry points and all places in the code that use them. It also fixes an additional name space collision between the kernel function psignal and the libc function of the same name by renaming the kernel psignal kern_psignal(). By introducing this change now we will ease future MFCs that change syscalls. Reviewed by: rwatson Approved by: re (bz)

While I'm here, eliminate unnecessary passing of "&length" to copystr(), where we don't actually care about the length of the copied string. Clean up the initialization of the exec map. In particular, use the correct size for an entry, and express that size in the same way that is used when an entry is allocated. The old size was one page too large. (This discrepancy originated in 2004 when I rewrote exec_map_first_page() to use sf_buf_alloc() instead of the exec map for mapping the first page of the executable.) Reviewed by: kib

SVN rev 205792 on 2010-03-28 13:13:22Z by ed Rename st_*timespec fields to st_*tim for POSIX 2008 compliance. A nice thing about POSIX 2008 is that it finally standardizes a way to obtain file access/modification/change times in sub-second precision, namely using struct timespec, which we already have for a very long time. Unfortunately POSIX uses different names. This commit adds compatibility macros, so existing code should still build properly. Also change all source code in the kernel to work without any of the compatibility macros. This makes it all a less ambiguous. I am also renaming st_birthtime to st_birthtim, even though it was a local extension anyway. It seems Cygwin also has a st_birthtim.

SVN rev 198508 on 2009-10-27 10:55:34Z by kib Current pselect(3) is implemented in usermode and thus vulnerable to well-known race condition, which elimination was the reason for the function appearance in first place. If sigmask supplied as argument to pselect() enables a signal, the signal might be delivered before thread called select(2), causing lost wakeup. Reimplement pselect() in kernel, making change of sigmask and sleep atomic. Since signal shall be delivered to the usermode, but sigmask restored, set TDP_OLDMASK and save old mask in td_oldsigmask. The TDP_OLDMASK should be cleared by ast() in case signal was not gelivered during syscall execution. Reviewed by: davidxu Tested by: pho MFC after: 1 month

New versions of these system calls provide the new ABI. The new system calls also use newer symbol versions in libc so old and new binaries will both work under new kernels. - Specific to 7.x: the kern_msgctl(), kern_semctl(), and kern_shmctl() functions now use ABI shims that transparently "rename" the functions to kern_new_*() for all new modules. Existing compat functions under the old names remain to provide compatibility for older kernel modules.

The internal VM object pointer for SHM regions has been moved into struct shmid_kernel. - The existing __semctl(), msgctl(), and shmctl() system call entries are now marked COMPAT7 and new versions of those system calls which support the new ABI are now present. - The new system calls are assigned to the FBSD-1.1 version in libc. The FBSD-1.0 symbols in libc now refer to the old COMPAT7 system calls. - A simplistic framework for tagging system calls with compatibility symbol versions has been added to libc. Version tags are added to system calls by adding an appropriate __sym_compat() entry to src/lib/libc/incldue/compat.h.

SVN rev 192895 on 2009-05-27 14:11:23Z by jamie Add hierarchical jails. A jail may further virtualize its environment by creating a child jail, which is visible to that jail and to any parent jails. Child jails may be restricted more than their parents, but never less. Jail names reflect this hierarchy, being MIB-style dot-separated strings. Every thread now points to a jail, the default being prison0, which contains information about the physical system. Prison0's root directory is the same as rootvnode; its hostname is the same as the global hostname, and its securelevel replaces the global securelevel. Note that the variable "securelevel" has actually gone away, which should not cause any problems for code that properly uses securelevel_gt() and securelevel_ge(). Some jail-related permissions that were kept in global variables and set via sysctls are now per-jail settings. The sysctls still exist for backward compatibility, used only by the now-deprecated jail(2) system call. Approved by: bz (mentor)

SVN rev 191673 on 2009-04-29 21:14:15Z by jamie Introduce the extensible jail framework, using the same "name=value" interface as nmount(2). Three new system calls are added: * jail_set, to create jails and change the parameters of existing jails. This replaces jail(2). * jail_get, to read the parameters of existing jails. This replaces the security.jail.list sysctl. * jail_remove to kill off a jail's processes and remove the jail. Most jail parameters may now be changed after creation, and jails may be set to exist without any attached processes. The current jail(2) system call still exists, though it is now a stub to jail_set(2). Approved by: bz (mentor)

SVN rev 189290 on 2009-03-02 23:26:30Z by jamie Extend the "vfsopt" mount options for more general use. Make struct vfsopt and the vfs_buildopts function public, and add some new fields to struct vfsopt (pos and seen), and new functions vfs_getopt_pos and vfs_opterror. Further extend the interface to allow reading options from the kernel in addition to sending them to the kernel, with vfs_setopt and related functions. While this allows the "name=value" option interface to be used for more than just FS mounts (planned use is for jails), it retains the current "vfsopt" name and <sys/mount.h> requirement.

Due to updated checks it is even possible to have jails without an IP address at all, which basically gives one a chroot with restricted process view, no networking,.. SCTP support was updated and supports IPv6 in jails as well. Cpuset support permits jails to be bound to specific processor sets after creation. Jails can have an unrestricted (no duplicate protection, etc.) name in addition to the hostname. The jail name cannot be changed from within a jail and is considered to be used for management purposes or as audit-token in the future. DDB 'show jails' command was added to aid debugging. Proper compat support permits 32bit jail binaries to be used on 64bit systems to manage jails. Also backward compatibility was preserved where possible: for jail v1 syscalls, as well as with user space management utilities. Both jail as well as prison version were updated for the new features.

SVN rev 186564 on 2008-12-29 12:58:45Z by ed Push down Giant inside sysctl. Also add some more assertions to the code. In the existing code we didn't really enforce that callers hold Giant before calling userland_sysctl(), even though there is no guarantee it is safe. Fix this by just placing Giant locks around the call to the oid handler. This also means we only pick up Giant for a very short period of time. Maybe we should add MPSAFE flags to sysctl or phase it out all together. I've also added SYSCTL_LOCK_ASSERT(). We have to make sure sysctl_root() and name2oid() are called with the sysctl lock held.

SVN rev 180808 on 2008-07-25 17:46:01Z by jhb MFC: Add cpuset, an api for thread to cpu binding and cpu resource grouping and assignment. This is mostly synched up with what is in HEAD with the following exceptions: - I didn't MFC any of the interrupt binding stuff as it requires other changes and I figured this change was large enough as it is. - The sched_affinity() implementation for ULE in HEAD depends on the newer CPU topology stuff as well as other changes in ULE. Rather than backport all of that, I implemented sched_affinity() using the existing CPU topology and ULE code in 7.x. Thus, any bugs in the ULE affinity stuff in 7 are purely my fault and not Jeff's. Note that, just as in HEAD, cpusets currently don't work on SCHED_4BSD (the syscalls will succeed, but they don't have any effect). Tested by: brooks, ps

Rework the routines to convert a 5.x+ statfs structure (with fixed-size 64-bit counters) to a 4.x statfs structure (with long-sized counters). - For block counters, we scale up the block size sufficiently large so that the resulting block counts fit into a the long-sized (long for the ABI, so 32-bit in freebsd32) counters. In 4.x the NFS client's statfs VOP did this already. This can lie about the block size to 4.x binaries, but it presents a more accurate picture of the ratios of free and available space. - For non-block counters, fix the freebsd32 stats converter to cap the values at INT32_MAX rather than losing the upper 32-bits to match the behavior of the 4.x statfs conversion routine in vfs_syscalls.c Approved by: re (kensmith)

- Split out kern_accept(), kern_getpeername(), and kern_getsockname() for use by ABI emulators. - Alter the interface of kern_recvit() somewhat. Specifically, go ahead and hard code UIO_USERSPACE in the uio as that's what all the callers specify. In place, add a new uioseg to indicate what type of pointer is in mp->msg_name. Previously it was always a userland address, but ABI emulators may pass in kernel-side sockaddrs. Also, remove the namelenp field and instead require the two places that used it to explicitly copy mp->msg_namelen out to userland. - Use the patched kern_recvit() to replace svr4_recvit() and the stock kern_sendit() to replace svr4_sendit(). - Use kern_bind() instead of stackgap use in ti_bind(). - Use kern_getpeername() and kern_getsockname() instead of stackgap in svr4_stream_ti_ioctl(). - Use kern_connect() instead of stackgap in svr4_do_putmsg(). - Use kern_getpeername() and kern_accept() instead of stackgap in svr4_do_getmsg(). - Retire the stackgap from SVR4 compat as it is no longer used.

- Add two new system calls: preadv() and pwritev() which are like readv() and writev() except that they take an additional offset argument and do not change the current file position. In SAT speak: preadv:readv::pread:read and pwritev:writev::pwrite:write. - Try to reduce code duplication some by merging most of the old kern_foov() and dofilefoo() functions into new dofilefoo() functions that are called by kern_foov() and kern_pfoov(). The non-v functions now all generate a simple uio on the stack from the passed in arguments and then call kern_foov(). For example, read() now just builds a uio and calls kern_readv() and pwrite() just builds a uio and calls kern_pwritev().

Correct the amount of data to allocate in these local copies of exec_copyin_strings() to catch up to rev 1.266 of kern_exec.c. This fixes panics on amd64 with compat binaries since exec_free_args() was freeing more memory than these functions were allocating and the mismatch could cause memory to be freed out from under other concurrent execs.

Do not allocate memory based on not-checked argument from userland. It can be used to panic the kernel by giving too big value. Fix it by moving allocation and size verification into kern_getfsstat(). This even simplifies kern_getfsstat() consumers, but destroys symmetry - memory is allocated inside kern_getfsstat(), but has to be freed by the caller.

Put on my peril sensitive sunglasses and add a flags field to the internal sysctl routines and state. Add some code to use it for signalling the need to downconvert a data structure to 32 bits on a 64 bit OS when requested by a 32 bit app. I tried to do this in a generic abi wrapper that intercepted the sysctl oid's, or looked up the format string etc, but it was a real can of worms that turned into a fragile mess before I even got it partially working. With this, we can now run 'sysctl -a' on a 32 bit sysctl binary and have it not abort. Things like netstat, ps, etc have a long way to go. This also fixes a bug in the kern.ps_strings and kern.usrstack hacks. These do matter very much because they are used by libc_r and other things.

Rework how we store process times in the kernel such that we always store the raw values including for child process statistics and only compute the system and user timevals on demand. - Fix the various kern_wait() syscall wrappers to only pass in a rusage pointer if they are going to use the result. - Add a kern_getrusage() function for the ABI syscalls to use so that they don't have to play stackgap games to call getrusage(). - Fix the svr4_sys_times() syscall to just call calcru() to calculate the times it needs rather than calling getrusage() twice with associated stackgap, etc. - Add a new rusage_ext structure to store raw time stats such as tick counts for user, system, and interrupt time as well as a bintime of the total runtime. A new p_rux field in struct proc replaces the same inline fields from struct proc (i.e. p_[isu]ticks, p_[isu]u, and p_runtime). A new p_crux field in struct proc contains the "raw" child time usage statistics. ruadd() has been changed to handle adding the associated rusage_ext structures as well as the values in rusage. Effectively, the values in rusage_ext replace the ru_utime and ru_stime values in struct rusage. These two fields in struct rusage are no longer used in the kernel. - calcru() has been split into a static worker function calcru1() that calculates appropriate timevals for user and system time as well as updating the rux_[isu]u fields of a passed in rusage_ext structure. calcru() uses a copy of the process' p_rux structure to compute the timevals after updating the runtime appropriately if any of the threads in that process are currently executing. It also now only locks sched_lock internally while doing the rux_runtime fixup. calcru() now only requires the caller to hold the proc lock and calcru1() only requires the proc lock internally. calcru() also no longer allows callers to ask for an interrupt timeval since none of them actually did. - calcru() now correctly handles threads executing on other CPUs. - A new calccru() function computes the child system and user timevals by calling calcru1() on p_crux. Note that this means that any code that wants child times must now call this function rather than reading from p_cru directly. This function also requires the proc lock. - This finishes the locking for rusage and friends so some of the Giant locks in exit1() and kern_wait() are now gone. - The locking in ttyinfo() has been tweaked so that a shared lock of the proctree lock is used to protect the process group rather than the process group lock. By holding this lock until the end of the function we now ensure that the process/thread that we pick to dump info about will no longer vanish while we are trying to output its info to the console.

- Replace wait1() with a kern_wait() function that accepts the pid, options, status pointer and rusage pointer as arguments. It is up to the caller to copyout the status and rusage to userland if needed. This lets us axe the 'compat' argument and hide all that functionality in owait(), by the way. This also cleans up some locking in kern_wait() since it no longer has to drop locks around copyout() since all the copyout()'s are deferred. - Convert owait(), wait4(), and the various ABI compat wait() syscalls to use kern_wait() rather than wait1() or wait4(). This removes a bit more stackgap usage. Tested on: i386 Compiled on: i386, alpha, amd64

Add BASIC i386 binary support for the amd64 kernel. This is largely stolen from the ia64/ia32 code (indeed there was a repocopy), but I've redone the MD parts and added and fixed a few essential syscalls. It is sufficient to run i386 binaries like /bin/ls, /usr/bin/id (dynamic) and p4. The ia64 code has not implemented signal delivery, so I had to do that. Before you say it, yes, this does need to go in a common place. But we're in a freeze at the moment and I didn't want to risk breaking ia64. I will sort this out after the freeze so that the common code is in a common place. On the AMD64 side, this required adding segment selector context switch support and some other support infrastructure. The %fs/%gs etc code is hairy because loading %gs will clobber the kernel's current MSR_GSBASE setting. The segment selectors are not used by the kernel, so they're only changed at context switch time or when changing modes. This still needs to be optimized. Approved by: re (amd64/* blanket)

Infrastructure tweaks to allow having both an Elf32 and an Elf64 executable handler in the kernel at the same time. Also, allow for the exec_new_vmspace() code to build a different sized vmspace depending on the executable environment. This is a big help for execing i386 binaries on ia64. The ELF exec code grows the ability to map partial pages when there is a page size difference, eg: emulating 4K pages on 8K or 16K hardware pages. Flesh out the i386 emulation support for ia64. At this point, the only binary that I know of that fails is cvsup, because the cvsup runtime tries to execute code in pages not marked executable. Obtained from: dfr (mostly, many tweaks from me).
