* This commit updates libarchive to be compatible withkientzle2007-08-182-183/+600
| | | | | | | | | | | | | | | | | | | | | | | | | GNU tar 1.17's implementation of --posix --sparse, at the cost of losing compatibility with GNU tar 1.16. Fortunately, the 1.17 implementation actually makes sense, so the libarchive code is now a bit more straightforward than before. Background: GNU tar 1.16 defined a new way to store sparse files in --posix archives. Unfortunately, the implementation incorrectly inserted several blocks of null padding after each such entry. As a result, non-GNU tar implementations saw the archive as truncated after any sparse entry. This was fixed in GNU tar 1.17 at the cost of losing compatibility with GNU tar 1.16 for this new format (which is not the default, so hopefully rarely used). Libarchive recently gained support for reading the GNU tar 1.16 formats; this commit updates it to read the GNU tar 1.17 variant instead.

* Make suid/sgid restore be "opportunistic" ifkientzle2007-08-122-16/+82
| | | | | | | | | | | | | | | | | | | | | | | | owner restore is not requested. If you ask for permissions to be restored but not owner, you will now get no error if suid/sgid bits cannot be set. (It's a security hole to restore suid/sgid bits if the owner/group aren't restored.) This fixes an obscure problem where a simple "tar -xf" with no other options will sometimes fail gratuitously because of suid/sgid bits. This is causing occasional problems for people using bsdtar as a drop-in replacement for "that other tar program." ;-) Note: If you do ask for owner restore, then suid/sgid restore failures still issue an error. This only suppresses the error in the case where an suid/sgid bit restore fails because of an owner mismatch and owner restore was not requested. Approved by: re (bmah) MFC after: 7 days
* Update the tests for reading the various GNU tar sparse formats.kientzle2007-08-121-75/+267
| | | | | | | | | | | | | | | In particular: * Include a second entry in all of the test archives (to catch errors with intermediate padding) * Test the GNU tar 1.17 version of "posix sparse format 1.0" instead of the GNU tar 1.16 version (the latter is no longer supported by GNU tar). Right now, libarchive fails this test because I originally implemented the GNU tar 1.16 version of "posix sparse format 1.0". I'll fix libarchive shortly.

* Improve error handling in libdisk while parsing the kern.geom.conftxt sysctl.rink2007-08-051-19/+38
| | | | | | | | | | | | | | | | | | | | | | | | Previously, any parse error will result in the calling program exiting with an unpleasant message. This change will cause libdisk to issue a warning and ignore lines it cannot parse instead of bluntly terminating the unfortunate enough program. This change will allow you to use sysinstall if you have a NTFS parition with a space in the name (such as 'Win Xp'). In such a case, a line like the following will appear in the kern.geom.conftxt output: 2 LABEL ntfs/Win Xp 209818635264 512 i 0 o 0 As the fields are space-separated, libdisk would go beserk and exit the program. This would happen if using FreeBSD 7.0 snapshot images (as GEOM_LABEL is in the installation kernel as well), thus making it impossible to install FreeBSD without renaming your NTFS paritions.

The default now is to send ASCONF immediately (except for the case of changing/deleting the last usable address). Approved by: re(ken smith)@freebsd.org

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | or replace (i.e., zdump) the environment after a call to setenv(), putenv() or unsetenv() has been made, a few changes were made. - getenv() will return the value from the new environ array. - setenv() was split into two functions: __setenv() which is most of the previous setenv() without checks on the name and setenv() which contains the checks before calling __setenv(). - setenv(), putenv() and unsetenv() will unset all previous values and call __setenv() on all entries in the new environ array which in turn adds them to the end of the envVars array. 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)

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.
