* libio: Implement vtable verification [BZ #20191]Florian Weimer2016-06-231-5/+13
| | | | | | | | | | | | | | | | | | | | This commit puts all libio vtables in a dedicated, read-only ELF section, so that they are consecutive in memory. Before any indirect jump, the vtable pointer is checked against the section boundaries, and the process is terminated if the vtable pointer does not fall into the special ELF section. To enable backwards compatibility, a special flag variable (_IO_accept_foreign_vtables), protected by the pointer guard, avoids process termination if libio stream object constructor functions have been called earlier. Such constructor functions are called by the GCC 2.95 libstdc++ library, and this mechanism ensures compatibility with old binaries. Existing callers inside glibc of these functions are adjusted to call the original functions, not the wrappers which enable vtable compatiblity. The compatibility mechanism is used to enable passing FILE * objects across a static dlopen boundary, too.

* Use "|" instead of "+" when combine the _IO_LINE_BUF and _IO_UNBUFFERED flagsFeng Gao2015-07-081-2/+2
| | | | | | | | Both of "_IO_UNBUFFERED" and "_IO_LINE_BUF" are the bit flags, but I find there are some codes looks like "_IO_LINE_BUF+_IO_UNBUFFERED", while some codes are "_IO_LINE_BUF|_IO_UNBUFFERED". I think the former is not good, even though the final result is same.

* Reset cached offset when reading to end of stream (BZ #17653)Siddhesh Poyarekar2014-12-041-1/+7
| | | | | | POSIX allows applications to switch file handles when a read results in an end of file. Unset the cached offset at this point so that it is queried again.
* ftell: seek to end only when there are unflushed bytes (BZ #17647)Siddhesh Poyarekar2014-12-041-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently we seek to end of file if there are unflushed writes or the stream is in write mode, to get the current offset for writing in append mode, which is the end of file. The latter case (i.e. stream is in write mode, but no unflushed writes) is unnecessary since it will only happen when the stream has just been flushed, in which case the recorded offset ought to be reliable. Removing that case lets ftell give the correct offset when it follows an ftruncate. The latter truncates the file, but does not change the file position, due to which it is permissible to call ftell without an intervening fseek call. Tested on x86_64 to verify that the added test case fails without the patch and succeeds with it, and that there are no additional regressions due to it. [BZ #17647] * libio/fileops.c (do_ftell): Seek only when there are unflushed writes. * libio/wfileops.c (do_ftell_wide): Likewise. * libio/tst-ftell-active-handler.c (do_ftruncate_test): New test case.

* Complete the removal of __gconv_translit_findFlorian Weimer2014-09-121-7/+2
| | | | | | | | | Prior to the 2.20 release, the function was just changed to fail unconditionally, in commit a1a6a401ab0a3c9f15fb7eaebbdcee24192254e8. This commit removes the function completely, including gconv bits which depend on it. This changes the gconv ABI, which is not a public interface.
* Fix offset computation for append+ mode on switching from read (BZ #16724)Siddhesh Poyarekar2014-05-271-1/+11
| | | | | | | | | | | | | | | | | The offset computation in write mode uses the fact that _IO_read_end is kept in sync with the external file offset. This however is not true when O_APPEND is in effect since switching to write mode ought to send the external file offset to the end of file without making the necessary adjustment to _IO_read_end. Hence in append mode, offset computation when writing should only consider the effect of unflushed writes, i.e. from _IO_write_base to _IO_write_ptr. The wiki has a detailed document that describes the rationale for offsets returned by ftell in various conditions: https://sourceware.org/glibc/wiki/File%20offsets%20in%20a%20stdio%20stream%20and%20ftell
* Fix offset caching for streams and use it for ftell (BZ #16680)Siddhesh Poyarekar2014-03-171-65/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ftell implementation was made conservative to ensure that incorrectly cached offsets never affect it. However, this causes problems for append mode when a file stream is rewound. Additionally, the 'clever' trick of using stat to get position for append mode files caused more problems than it solved and broke old behavior. I have described the various problems that it caused and then finally the solution. For a and a+ mode files, rewinding the stream should result in ftell returning 0 as the offset, but the stat() trick caused it to (incorrectly) always return the end of file. Now I couldn't find anything in POSIX that specifies the stream position after rewind() for a file opened in 'a' mode, but for 'a+' mode it should be set to 0. For 'a' mode too, it probably makes sense to keep it set to 0 in the interest of retaining old behavior. The initial file position for append mode files is implementation defined, so the implementation could either retain the current file position or move the position to the end of file. The earlier ftell implementation would move the offset to end of file for append-only mode, but retain the old offset for a+ mode. It would also cache the offset (this detail is important). My patch broke this and would set the initial position to end of file for both append modes, thus breaking old behavior. I was ignorant enough to write an incorrect test case for it too. The Change: I have now brought back the behavior of seeking to end of file for append-only streams, but with a slight difference. I don't cache the offset though, since we would want ftell to query the current file position through lseek while the stream is not active. Since the offset is moved to the end of file, we can rely on the file position reported by lseek and we don't need to resort to the stat() nonsense. Finally, the cache is always reliable, except when there are unflished writes in an append mode stream (i.e. both a and a+). In the latter case, it is safe to just do an lseek to SEEK_END. The value can be safely cached too, since the file handle is already active at this point. Incidentally, this is the only state change we affect in the file handle (apart from taking locks of course). I have also updated the test case to correct my impression of the initial file position for a+ streams to the initial behavior. I have verified that this does not break any existing tests in the testsuite and also passes with the new tests.
* Use cached offset in ftell when reliableSiddhesh Poyarekar2014-03-041-6/+28
| | | | | | | | | | | | | | | | | | | | | | | | The cached offset is reliable to use in ftell when the stream handle is active. We can consider a stream as being active when there is unflushed data. However, even in this case, we can use the cached offset only when the stream is not being written to in a+ mode, because this case may have unflushed data and a stale offset; the previous read could have sent it off somewhere other than the end of the file. There were a couple of adjustments necessary to get this to work. Firstly, fdopen now ceases to use _IO_attach_fd because it sets the offset cache to the current file position. This is not correct because there could be changes to the file descriptor before the stream handle is activated, which would not get reflected. A similar offset caching action is done in _IO_fwide, claiming that wide streams have 'problems' with the file offsets. There don't seem to be any obvious problems with not having the offset cache available, other than that it will have to be queried in a subsequent read/write/seek. I have removed this as well. The testsuite passes successfully with these changes on x86_64.
* Separate ftell from fseek logic and avoid modifying FILE data (#16532)Siddhesh Poyarekar2014-03-041-30/+75
| | | | | | | | | | | | | | | ftell semantics are distinct from fseek(SEEK_CUR) especially when it is called on a file handler that is not yet active. Due to this caveat, much care needs to be taken while modifying the handler data and hence, this first iteration on separating out ftell focusses on maintaining handler data integrity at all times while it figures out the current stream offset. The result is that it makes a syscall for every offset request. There is scope for optimizing this by caching offsets when we know that the handler is active. A simple way to find out is when the buffers have data. It is not so simple to find this out when the buffer is empty without adding some kind of flag.

Fix BZ#11741 properly by checking the return value from _IO_padn() in stdio-common/vfprintf.c.

| | | | | | | | | | | In BZ #12724, partial support for POSIX 2008 fclose behavior was added. Since it isn't entirely conforming to the spec, some applications are known to be breaking in this intermediate state. So revert the partial support until we can get things fully implemented.
