* hurd: Fix poll and select POSIX compliancy details about errorsSamuel Thibault2019-08-301-41/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the following: - On error, poll must not return without polling, including EBADF, and instead report POLLHUP/POLLERR/POLLNVAL - Select must report EBADF if some set contains an invalid FD. The idea is to move error management to after all select calls, in the poll/select final treatment. The error is instead recorded in a new `error' field, and a new SELECT_ERROR bit set. Thanks Svante Signell for the initial version of the patch. * hurd/hurdselect.c (SELECT_ERROR): New macro. (_hurd_select): - Add `error' field to `d' structures array. - If a poll descriptor is bogus, set EBADF, but continue with a zero timeout. - Go through the whole fd_set, not only until _hurd_dtablesize. Return EBADF there is any bit set above _hurd_dtablesize. - Do not request io_select on bogus descriptors (SELECT_ERROR). - On io_select request error, record the error. - On io_select bogus reply, use EIO error code. - On io_select bogus or error reply, record the error. - Do not destroy reply port for bogus FDs. - On error, make poll set POLLHUP in the EPIPE case, POLLNVAL in the EBADF case, or else POLLERR. - On error, make select simulated readiness.
* hurd: Fix timeout handling in _hurd_selectRichard Braun2019-08-302-40/+79
| | | | | | | | | | | | | | | | | | | Rely on servers to implement timeouts, so that very short values (including 0) don't make mach_msg return before valid replies can be received. The purpose of this scheme is to guarantee a full client-server round-trip, whatever the timeout value. This change depends on the new io_select_timeout RPC being implemented by servers. * hurd/Makefile (user-interfaces): Add io_reply and io_request. * hurd/hurdselect.c: Include <sys/time.h>, <hurd/io_request.h> and <limits.h>. (_hurd_select): Replace the call to __io_select with either __io_select_request or __io_select_timeout_request, depending on the timeout. Count the number of ready descriptors (replies for which at least one type bit is set). Implement the timeout locally when there is no file descriptor.
* hurd: Fix _hurd_select for single fd setsRichard Braun2019-08-301-4/+1
| | | | | | | | | | | | The function attempts to optimize this case by performing one IPC system call with the timeout included among the parameters, but in the absence of a reply, it will call mach_msg again with the same timeout later, effectively doubling the total timeout of the select/poll call. Remove this optimization for the time being. * hurd/hurdselect.c (_hurd_select): Always call __io_select with no timeout.

* Fix -Wempty-body warnings in Hurd-specific code.Joseph Myers2019-02-271-4/+6
| | | | | | | | | | | | | | | | This patch fixes -Wempty-body warnings in Hurd-specific code that show up building glibc with -Wextra. Note: there also such warnings on many platforms arising from the default definition of HP_TIMING_NOW in sysdeps/generic/hp-timing.h, but no change there is proposed in this patch because of other changes under discussion in that area that would result in a nonempty definition. Tested with build-many-glibcs.py. * hurd/hurdinit.c (_hurd_init): Use braces around empty body of an if statement.

* Break some lines before not after operators.Joseph Myers2019-02-2215-79/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GNU Coding Standards specify that line breaks in expressions should go before an operator, not after one. This patch fixes various code to do this. It only changes code that appears to be mostly following GNU style anyway, not files and directories with substantially different formatting. It is not exhaustive even for files using GNU style (for example, changes to sysdeps files are deferred for subsequent cleanups). Some files changed are shared with gnulib, but most are specific to glibc. Changes were made manually, with places to change found by grep (so some cases, e.g. where the operator was followed by a comment at end of line, are particularly liable to have been missed by grep, but I did include cases where the operator was followed by backslash-newline). This patch generally does not attempt to address other coding style issues in the expressions changed (for example, missing spaces before '(', or lack of parentheses to ensure indentation of continuation lines properly reflects operator precedence).

* Add __v*printf_internal with flags argumentsZack Weinberg2018-12-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a lot more printf variants than there are scanf variants, and the code for setting up and tearing down their custom FILE variants around the call to __vf(w)printf is more complicated and variable. Therefore, I have added _internal versions of all the v*printf variants, rather than introducing helper routines so that they can all directly call __vf(w)printf_internal, as was done with scanf. As with the scanf changes, in this patch the _internal functions still look at the environmental mode bits and all callers pass 0 for the flags parameter. Several of the affected public functions had _IO_ name aliases that were not exported (but, in one case, appeared in libio.h anyway); I was originally planning to leave them as aliases to avoid having to touch internal callers, but it turns out ldbl_*_alias only work for exported symbols, so they've all been removed instead. It also turns out there were hardly any internal callers. _IO_vsprintf and _IO_vfprintf *are* exported, so those two stick around. Summary for the changes to each of the affected symbols: _IO_vfprintf, _IO_vsprintf: All internal calls removed, thus the internal declarations, as well as uses of libc_hidden_proto and libc_hidden_def, were also removed. The external symbol is now exposed via uses of ldbl_strong_alias to __vfprintf_internal and __vsprintf_internal, respectively. _IO_vasprintf, _IO_vdprintf, _IO_vsnprintf, _IO_vfwprintf, _IO_vswprintf, _IO_obstack_vprintf, _IO_obstack_printf: All internal calls removed, thus declaration in internal headers were also removed. They were never exported, so there are no aliases tying them to the internal functions. I.e.: entirely gone. __vsnprintf: Internal calls were always preceded by macros such as #define __vsnprintf _IO_vsnprintf, and #define __vsnprintf vsnprintf The macros were removed and their uses replaced with calls to the new internal function __vsnprintf_internal. Since there were no internal calls, the internal declaration was also removed. The external symbol is preserved with ldbl_weak_alias to ___vsnprintf. __vfwprintf: All internal calls converted into calls to __vfwprintf_internal, thus the internal declaration was removed. The function is now a wrapper that calls __vfwprintf_internal. The external symbol is preserved. __vswprintf: Similarly, but no external symbol. __vasprintf, __vdprintf, __vfprintf, __vsprintf: New internal wrappers. Not exported. vasprintf, vdprintf, vfprintf, vsprintf, vsnprintf, vfwprintf, vswprintf, obstack_vprintf, obstack_printf: These functions used to be aliases to the respective _IO_* function, they are now aliases to their respective __* functions. Tested for powerpc and powerpc64le.

* hurd: Fix O_DIRECTORY | O_NOFOLLOWSamuel Thibault2018-03-182-1/+3
| | | | | | | | | | | | | Appending / to the path to be looked up would make us always follow a final symlink, even with O_NOTRANS (since the final resolution is after the '/').

I used __ssize_t and __gnuc_va_list in a handful of headers where namespace cleanliness might be relevant even though they're internal-use-only. In all other cases, I used the public-namespace name. There are a tiny handful of places where I left a use of 'struct _IO_FILE' alone, because it was being used together with 'struct _IO_FILE_plus' or 'struct _IO_FILE_complete' in the same arithmetic expression. Because this patch was almost entirely done with search and replace, I may have introduced indentation botches. I did proofread the diff, but I may have missed something.
