* Disable support for /dev/ptmx in FreeBSD 7.0. While it's a good idea inRobert Watson2007-12-061-0/+4
| | | | | | | | | | | | | | | | | | | principle, the current devfs-based cloning facilit makes the current user<->kernel protocol for allocating new pts nodes difficult or impossible to do without leading to resource leaks or race conditions. We tentatively plan to reintroduce ptmx/pts support in FreeBSD 7.1 once a fixed version has settled out in HEAD. People who really want to run with the current code can re-enable it but it will require tweaking conf files and unifdef'ing it. By removing it now before the release, we avoid having to support the current allocation protocol in future releases in order to provide backwards compatibility with older libc's.

Calling __setenv() instead of setenv() is done to avoid the temporary replacement of the '=' in a string with a NUL byte. Some strings may be read-only data. Added more regression checks for clearing the environment array. Replaced gettimeofday() with getrusage() in timing regression check for better accuracy. Fixed an off-by-one bug in __remove_putenv() in the use of memmove(). This went unnoticed due to the allocation of double the number of environ entries when building envVars. Fixed a few spelling mistakes in the comments. Reviewed by: ache Approved by: wes Approved by: re (kensmith) Notes: svn path=/head/; revision=171525

This meant a free was called without an increment to refcnt, added increment like rest of code. - There was a case, unlikely, when the scope of the destination changed (this is a TSNH case). In that case, it would not free the alloc'ed asoc (in sctp_input.c). - When listed addresses found a colliding cookie/Init, then the collided upon tcb was not unlocked in sctp_pcb.c - Add error checking on arguments of sctp_sendx(3) to prevent it from referencing a NULL pointer. - Fix an error return of sctp_sendx(3), it was returing ENOMEM not -1. - Get assoc id was changed to use the sanctified socket api method for getting a assoc id (PEER_ADDR_INFO instead of PEER_ADDR_PARAMS). - Fix it so a peeled off socket will get a proper error return if it trys to send to a different address then it is connected to. - Fix so that select_a_stream can avoid an endless loop that could hang a caller. - time_entered (state set time) was not being set in all cases to the time we went established.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | particular: SYSCALL() makes a syscall, with errno handling, and continues execution directly after the macro in the non-error case. RSYSCALL() is just like SYSCALL(), but returns after success. Both SYSCALL(name) and RSYSCALL(name) export "__sys_name" as a strong symbol, with "_name" and "name" as weak aliases. PSEUDO() is just like RSYSCALL(), but skipping the "name" weak alias. It still does "__sys_name" and "_name". Change i386 to add errno handling to PSEUDO. The same for amd64 and sparc64, with appear to have copied the behavior. ia64 was correct (as was alpha). Just remove some apparently unused variants of the macros. (untested!) I believe powerpc is correct. Fix arm to not export "name" from the PSEUDO case. Remove apparently extra unused variants. (untested!) The errno problem manifested on i386/amd64/sparc64 by having "PSEUDO" classified syscalls return without setting errno. eg: "addr = mmap()" could return with "addr" = 22 instead of setting errno to 22 and returning -1.

Convert all calls to POSIX from historic BSD API: - unsetenv returns an int. - putenv takes a char * instead of const char *. - putenv no longer makes a copy of the input string. - errno is set appropriately for POSIX. Exceptions involve bad environ variable and internal initialization code. These both set errno to EFAULT. Several patches to base utilities to handle the POSIX changes from Andrey Chernov's previous commit. A few I re-wrote to use setenv() instead of putenv(). New regression module for tools/regression/environ to test these functions. It also can be used to test the performance. Bump __FreeBSD_version to 700050 due to API change.
