2015-02-09make sigprocmask(2) not take the kernel lockMartin Pelikan
Tests on a 4-core CPU show setjmp(3) run four times as fast under load. discussed on tech@ some time ago, now by kettenis and guenther, ok deraadt
2015-01-30Fix mbuf leak in Linux compat setsockopt() in the error path whenTodd C. Miller
optval is not valid. Found by Maxime Villard. OK bluhm@
2015-01-26Move the "stackgap" from the stack into its own page at a random address.Mark Kettenis
This allows us the unmap the initial part of the stack, such that it can't be used as a staging area for ROP (or other) attacks. ok guenther@, tedu@
2015-01-21Ubreak the tree by using "struct ifreq" instead of "struct linux_ifreq".Martin Pieuchot
2015-01-21Delete option COMPAT_43: support for pre-sa_len binaries has been obsoletePhilip Guenther
for a couple decades. Keep the OSIOCGIFCONF ioctl to support COMPAT_LINUX but move the rest of the Linux-specific ioctl() handling into linux_socket.c This lets struct osockaddr finally move from sys/socket.h to protocols/talkd.h ok krw@ deraadt@ mpi@
2015-01-19Prefer linux_sockaddr over osockaddr, so the latter can go away.Philip Guenther
sys_socket() supports SOCK_{CLOEXEC,NONBLOCK} now, so build on that. doaccept() supports the non-inheriting-of-O_NONBLOCK, so build on that. Merge compat_sys_{accept,send,recv}() into their only callers. Lie a little and use struct sockaddr in the linux socket syscall args when it's a return argument to avoid a bunch a casts. Delete many other unnecessary sockaddr casts verified with a curl Linux binary
2014-12-16must include lock.h to play with locksTed Unangst
2014-12-16primary change: move uvm_vnode out of vnode, keeping only a pointer.Ted Unangst
objective: vnode.h doesn't include uvm_extern.h anymore. followup changes: include uvm_extern.h or lock.h where necessary. ok and help from deraadt
2014-12-05Explicitly include <net/if_var.h> instead of pulling it in <net/if.h>.Martin Pieuchot

2014-11-16Replace a plethora of historical protection options with justTheo de Raadt
PROT_NONE, PROT_READ, PROT_WRITE, and PROT_EXEC from mman.h. PROT_MASK is introduced as the one true way of extracting those bits. Remove UVM_ADV_* wrapper, using the standard names. ok doug guenther kettenis

months that I broke it before the 5.5 release. confirmed as not being required by ports by sthen@, ajacoutot@, dcoppa@

2014-04-07Retire kernel support for SO_DONTROUTE, this time without breakingMartin Pieuchot
localhost connections. The plan is to always use the routing table for addresses and routes resolutions, so there is no future for an option that wants to bypass it. This option has never been implemented for IPv6 anyway, so let's just remove the IPv4 bits that you weren't aware of. Tested a least by lteo@, guenther@ and chrisz@, ok mikeb@, benno@
2014-03-30Eliminates struct pcred by moving the real and saved ugids intoPhilip Guenther
struct ucred; struct process then directly links to the ucred Based on a discussion at c2k10 or so before noting that FreeBSD and NetBSD did this too. ok matthew@

2014-03-26Move p_emul and p_sigcode from proc to process.Philip Guenther
Tweak the handling of ktrace EMUL when changing ktracing: only generate one per process (not one per thread) and pass the correct proc pointer down to the VFS layer. Permit generating of NAMI and CSW records inside ktrace(2) itself. ok deraadt@ millert@
2014-03-24The kernel isn't involved in times(3); <sys/times.h> should never bePhilip Guenther
included there
2014-02-13Instead of iterating over the per-interface list of addresses toMartin Pieuchot
find the link-layer address of an interface, use the pointer to the sockaddr_dl already present in the interface's descriptor. Tested for regression by pirofti@ with opera.
2014-02-12Eliminate the exit sig handling, which was only invokable via thePhilip Guenther
Linux-compat clone() syscall when *not* using CLONE_THREAD. pirofti@ confirms Opera runs in compat without this, so out it goes; one less hair to choke on in kern_exit.c ok tedu@ pirofti@
2014-01-23Try to cope better with void pointer to int usage cases.Paul Irofti
Use intptr_t for such cases. More casts/types should be improved in this file. Tested with syscall regression tests from IBM.

2014-01-20Threads can't be zombies, only processes, so change zombproc to zombprocess,Philip Guenther
make it a list of processes, and change P_NOZOMBIE and P_STOPPED from thread flags to process flags. Add allprocess list for the code that just wants to see processes. ok tedu@

2013-11-03Remove a bunch of a.out related macros.Paul Irofti
2013-11-03Regenerate.Paul Irofti
a.out removal led to linux_sys_uselib being obsoleted.
2013-11-03Remove a.out support from compat_linux(8).Paul Irofti
Tested with the syscall regression test suite from IBM and Opera. Requested by deraadt@.
2013-10-31Fix readdir_with_callback() after cookies removal.Paul Irofti
The non-cookie path was probably always broken and never used. The file descriptor offset was never updated after a read so glibc and other syscall consumers would end-up in an infinite loop. Tested with the syscalls regression suite from IBM and with opera.

2013-10-25Unimplement stime() and settimeofday(): why are you using a Linux-compatPhilip Guenther
binary to change the system time? ok pirofti@
2013-10-25regenPhilip Guenther
2013-10-25Start to deal with the time_t change's effect on compat/linux:Philip Guenther
- add Linux versions of struct rusage, timeval, and itimerval and conversion functions for them - add Linux versions of getrusage(), gettimeofday(), {set,get}itimer(), and nanosleep() - fix various inconsistencies in naming of Linux versions of types and conversion functions - add mappings for LINUX_CLOCK_{PROCESS,THREAD}_CPUTIME_ID to the native versions Originally written months ago as part of the time_t work; long memory, prodding, and ok from pirofti@
2013-09-14miod completed the ELF conversion (and didn't even use this compat bit),Philip Guenther
so this old compat is dead
2013-08-13regenPhilip Guenther
2013-08-13Switch time_t, ino_t, clock_t, and struct kevent's ident and dataPhilip Guenther
members to 64bit types. Assign new syscall numbers for (almost all) the syscalls that involve the affected types, including anything with time_t, timeval, itimerval, timespec, rusage, dirent, stat, or kevent arguments. Add a d_off member to struct dirent and replace getdirentries() with getdents(), thus immensely simplifying and accelerating telldir/seekdir. Build perl with -DBIG_TIME. Bump the major on every single base library: the compat bits included here are only good enough to make the transition; the T32 compat option will be burned as soon as we've reached the new world are are happy with the snapshots for all architectures. DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead. Much assistance in fixing userland issues from deraadt@ and tedu@ and build assistance from todd@ and otto@
