* Our fts(3) API, as inherited from 4.4BSD, suffers from integeryar2008-01-261-18/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fields in FTS and FTSENT structs being too narrow. In addition, the narrow types creep from there into fts.c. As a result, fts(3) consumers, e.g., find(1) or rm(1), can't handle file trees an ordinary user can create, which can have security implications. To fix the historic implementation of fts(3), OpenBSD and NetBSD have already changed <fts.h> in somewhat incompatible ways, so we are free to do so, too. This change is a superset of changes from the other BSDs with a few more improvements. It doesn't touch fts(3) functionality; it just extends integer types used by it to match modern reality and the C standard. Here are its points: o For C object sizes, use size_t unless it's 100% certain that the object will be really small. (Note that fts(3) can construct pathnames _much_ longer than PATH_MAX for its consumers.) o Avoid the short types because on modern platforms using them results in larger and slower code. Change shorts to ints as follows: - For variables than count simple, limited things like states, use plain vanilla `int' as it's the type of choice in C. - For a limited number of bit flags use `unsigned' because signed bit-wise operations are implementation-defined, i.e., unportable, in C. o For things that should be at least 64 bits wide, use long long and not int64_t, as the latter is an optional type. See FTSENT.fts_number aka FTS.fts_bignum. Extending fts_number `to satisfy future needs' is pointless because there is fts_pointer, which can be used to link to arbitrary data from an FTSENT. However, there already are fts(3) consumers that require fts_number, or fts_bignum, have at least 64 bits in it, so we must allow for them. o For the tree depth, use `long'. This is a trade-off between making this field too wide and allowing for 64-bit inode numbers and/or chain-mounted filesystems. On the one hand, `long' is almost enough for 32-bit filesystems on a 32-bit platform (our ino_t is uint32_t now). On the other hand, platforms with a 64-bit (or wider) `long' will be ready for 64-bit inode numbers, as well as for several 32-bit filesystems mounted one under another. Note that fts_level has to be signed because -1 is a magic value for it, FTS_ROOTPARENTLEVEL. o For the `nlinks' local var in fts_build(), use `long'. The logic in fts_build() requires that `nlinks' be signed, but our nlink_t currently is uint16_t. Therefore let's make the signed var wide enough to be able to represent 2^16-1 in pure C99, and even 2^32-1 on a 64-bit platform. Perhaps the logic should be changed just to use nlink_t, but it can be done later w/o breaking fts(3) ABI any more because `nlinks' is just a local var. This commit also inludes supporting stuff for the fts change: o Preserve the old versions of fts(3) functions through libc symbol versioning because the old versions appeared in all our former releases. o Bump __FreeBSD_version just in case. There is a small chance that some ill-written 3-rd party apps may fail to build or work correctly if compiled after this change. o Update the fts(3) manpage accordingly. In particular, remove references to fts_bignum, which was a FreeBSD-specific hack to work around the too narrow types of FTSENT members. Now fts_number is at least 64 bits wide (long long) and fts_bignum is an undocumented alias for fts_number kept around for compatibility reasons. According to Google Code Search, the only big consumers of fts_bignum are in our own source tree, so they can be fixed easily to use fts_number. o Mention the change in src/UPDATING.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | is also implemented in glibc and is used by a number of existing applications (mysql, firefox, etc). This mutex type is a default mutex with the additional property that it spins briefly when attempting to acquire a contested lock, doing trylock operations in userland before entering the kernel to block if eventually unsuccessful. The expectation is that applications requesting this mutex type know that the mutex is likely to be only held for very brief periods, so it is faster to spin in userland and probably succeed in acquiring the mutex, than to enter the kernel and sleep, only to be woken up almost immediately. This can help significantly in certain cases when pthread mutexes are heavily contended and held for brief durations (such as mysql). Spin up to 200 times before entering the kernel, which represents only a few us on modern CPUs. No performance degradation was observed with this value and it is sufficient to avoid a large performance drop in mysql performance in the heavily contended pthread mutex case. The libkse implementation is a NOP. Reviewed by: jeff MFC after: 3 days

* The problem is: currently our single byte ctype(3) functions are brokenache2007-10-133-23/+56
| | | | | | | | | | | | | | | | | | | | | | | | | for wide characters locales in the argument range >= 0x80 - they may return false positives. Example 1: for UTF-8 locale we currently have: iswspace(0xA0)==1 and isspace(0xA0)==1 (because iswspace() and isspace() are the same code) but must have iswspace(0xA0)==1 and isspace(0xA0)==0 (because there is no such character and all others in the range 0x80..0xff for the UTF-8 locale, it keeps ASCII only in the single byte range because our internal wchar_t representation for UTF-8 is UCS-4). Example 2: for all wide character locales isalpha(arg) when arg > 0xFF may return false positives (must be 0). (because iswalpha() and isalpha() are the same code) This change address this issue separating single byte and wide ctype and also fix iswascii() (currently iswascii() is broken for arguments > 0xFF). This change is 100% binary compatible with old binaries. Reviewied by: i18n@

| | | | | | | | | | | | | | | | | | | | | | | | | | setenv(3) by tracking the size of the memory allocated instead of using strlen() on the current value. 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.

If the restore is running as root, it will always be able to restore all extended attributes. If it is not running as root, it makes a best effort to set them. Using the -v command line flag or the `verbose' command in interactive mode will display all the extended attributes being set on files (and at the end on directories) that are being restored. It will note any extended attributes that could not be set. The extended attributes are placed on the dump image immediately following each file's data. Older versions of restore can work with the newer dump images. Old versions of restore will correctly restore the file data and then (silently) skip over the extended attribute data and proceed to the next file. This resolves PR 93085 which will be closed once the code has been MFC'ed. Note that this code will not compile until these header files have been updated: <protocols/dumprestore.h> and <sys/extattr.h>.
