2003-10-08originally from cb@netbsd.org, adapted by provosNikolay Sturm
itojun@ ok fix a race condition between path resolution in userland and the subsequent namei(): inform the kernel portion of valid filenames and then disallow symlink lookups for those filenames by means of a hook in namei(). with suggestions from provos@ also, add (currently unused) seqnr field to struct systrace_replace, from provos@
2003-10-03Merge tty_attach() in ttymalloc() and tty_detach() in ttyfree(). The need forMiod Vallat
separate tty registering is gone now that sparc has switched to wscons, and this makes the code less error-prone. Also, remove tests for ttymalloc() failure, since it uses M_WAITOK. ok millert@ deraadt@, tested by various people as well besides me...
2003-10-03Bring several fixes from FreeBSD to our current pipe implementation:Miod Vallat
- when allocating or growing a pipe buffer is not possible, do not panic but report the error and handle it correctly. (1.73) - "The pipe_write() code was locking the pipe without busying it first in certain cases, and a close() by another process could potentially rip the pipe out from under the (blocked) locking operation." (from Al Viro, 1.81) - "Remove test in pipe_write() which causes write(2) to return EAGAIN on a non-blocking pipe in cases where select(2) returns the file descriptor as ready for write. This in turns causes libc_r, for one, to busy wait in such cases. Note: it is a quick performance fix, a more complex fix might be required in case this turns out to have unexpected side effects." (1.141)

now call the poll backend. With this change we implement greater poll(2) functionality instead of emulating it via the select backend. Adapted from NetBSD and including some changes from FreeBSD. Tested by many, deraadt@ OK

2003-08-21emulation is now controlled by sysctl. changes:Ted Unangst
add e_flags to struct emul. this stores on/off and native flags. check for emul enabled in check_exec(). gather all the emuls into a emulsw so a sysctl can find them. create sysctl. move maxhdrsiz calcualation into init_main so it cleans up sys_execve codepath. teach sysctl utility to grok kern.emul hierarchy. requested and ok deraadt@ some comments from mickey@

2003-08-15change arguments to suser. suser now takes the process, and a flagsTed Unangst
argument. old cred only calls user suser_ucred. this will allow future work to more flexibly implement the idea of a root process. looks like something i saw in freebsd, but a little different. use of suser_ucred vs suser in file system code should be looked at again, for the moment semantics remain unchanged. review and input from art@ testing and further review miod@

2003-08-03Implement the WCONTINUED flag to the wait(2) family of syscalls and theTodd C. Miller
associated WIFCONTINUED macro as per 1003.1-2001. Adapted from FreeBSD. A minor amount of trickiness is involved here. The value for WCONTINUED is chosen in such a way that _WSTATUS(_WCONTINUED) == _WSTOPPED and the WIFSTOPPED macro has been modified such that WIFSTOPPED(_WCONTINUED) != _WSTOPPED. This means we don't need to add an extra check to the WIFSIGNALED and WIFSTOPPED macros. deraadt@ OK.

2003-06-25implement new means of manipulating buf queues, bufq.Ted Unangst
accessed with BUFQ macros, bufq structs support extensible, potentially changable algorithms and queue formats. the current default scheme should support nice priority based queuing, but is missing some vfs_bio.c support. only on wd.c for now, other drivers are easy converts. as a side bonus, this makes the driver code look cleaner. idea for the name comes from netbsd, but this scheme is incompatible. thanks to various people for testing. ok grange@
