* Fix Linux fcntl OFD locks for non-LFS architectures (BZ#20251)Adhemerval Zanella2018-06-261-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the OFD ("file private") locks for architectures that support non-LFS flock definition (__USE_FILE_OFFSET64 not defined). The issue in this case is both F_OFD_{GETLK,SETLK,SETLKW} and F_{SET,GET}L{W}K64 expects a flock64 argument and when using old F_OFD_* flags with a non LFS flock argument the kernel might interpret the underlying data wrongly. Kernel idea originally was to avoid using such flags in non-LFS syscall, but since GLIBC uses fcntl with LFS semantic as default it is possible to provide the functionality and avoid the bogus struct kernel passing by adjusting the struct manually for the required flags. The idea follows other LFS interfaces that provide two symbols: 1. A new LFS fcntl64 is added on default ABI with the usual macros to select it for FILE_OFFSET_BITS=64. 2. The Linux non-LFS fcntl use a stack allocated struct flock64 for F_OFD_{GETLK,SETLK,SETLKW} copy the results on the user provided struct. 3. Keep a compat symbol with old broken semantic for architectures that do not define __OFF_T_MATCHES_OFF64_T. So for architectures which defines __USE_FILE_OFFSET64, fcntl64 will aliased to fcntl and no adjustment would be required. So to actually use F_OFD_* with LFS support the source must be built with LFS support (_FILE_OFFSET_BITS=64). Also F_OFD_SETLKW command is handled a cancellation point, as for F_SETLKW{64}. Checked on x86_64-linux-gnu and i686-linux-gnu.

* manual: Replace summary.awk with summary.pl.Rical Jasan2017-06-151-230/+115

If invalid @standards syntax is detected, summary.pl will fail, reporting all errors. Failure and error reporting is disabled for now, however, since much of the manual is still incomplete wrt. header and standards annotations. Note that the sorting order of the Summary has changed; summary.pl respects the locale, like summary.awk did, but the use of LC_ALL=C is introduced in the Makefile. Other notable deviations are improved detection of the annotated elements' names, which are used for sorting, and improved detection of the @node used to reference into the manual. The most noticeable difference in the rendered Summary is that entries may now contain multiple lines, one for each header and standard combination. summary.pl accepts a `--help' option, which details the expected syntax of @standards.

* posix: Implement preadv2 and pwritev2Adhemerval Zanella2017-05-311-0/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support of preadv2 and pwritev2 which are similar to preadv/pwritev but with an extra flag argument. As for preadv/pwritev both interfaces are added a non-standard GNU API. For default 'posix' implementation trying to emulate the Linux supported flags is troublesome: * We can not temporary change the file state of the O_DSYNC and O_SYNC flags to emulate RWF_{D}SYNC (attempts to change the state of using fcntl are silently ignored). * IOCB_HIPRI requires the file opened in O_DIRECT and uses an internal semantic not provided by any other flag (O_NONBLOCK for instance). So default sysdeps/posix implementations fails with EOPNOTSUPP for any non supported flag (which are none currently) calls generic preadv/pwritev. Basically this implementation supports only preadv2 called as preadv (with flags sets to 0). The Linux one uses the preadv2/pwritev2 syscall if defined, otherwise it call preadv/writev. Instead of using the previous __ASSUME_* to unconditionally issue the syscall (and avoid building the fallback routine), it call pread/write if the preadv2/pwritev2 syscalls fails. The idea is just avoid adding another __ASSUME_* and checking each architecture on every kernel bump and simplify code conditionals.

* manual: Convert @tables of variables to @vtables.Rical Jasan2016-12-211-20/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Texinfo @vindex commands add entries to the Variable and Constant Macro Index. Similarly, @items in @vtables are automatically indexed. A number of @tables exist where all @items are @vindexed or all @items are variables, but not indexed, suggesting an optimization by converting such @tables to @vtables and dropping the @vindex. Using a @vtable provides a context for processing @items whereby it can be known the @items should have header and standards annotations. This commit converts @tables of such @items to @vtables in order to establish a framework for automated processing. A pleasant consequence of these changes is that @items previously lacking a @vindex are present in the Variable and Constant Macro Index now. @vindex entries previously detected by summary.awk will still be detected as @items with appropriate annotations. The @vtable of the NSS databases is converted to a @table because 1) those @items are not variables (and will no longer appear in the Variable and Constant Macro Index) and 2) they do not need header and standards annotations, so the incorrect context is fixed. * manual/nss.texi: Change incorrect @vtable to @table. * manual/arith.texi: Convert @tables of variables to @vtables and remove unnecessary indexing. * manual/filesys.texi: Likewise. * manual/llio.texi: Likewise. * manual/memory.texi: Likewise. * manual/process.texi: Likewise. * manual/resource.texi: Likewise. * manual/search.texi: Likewise. * manual/signal.texi: Likewise. * manual/socket.texi: Likewise. * manual/stdio.texi: Likewise. * manual/sysinfo.texi: Likewise. * manual/syslog.texi: Likewise. * manual/terminal.texi: Likewise. * manual/time.texi: Likewise. * manual/users.texi: Likewise.
