* Remove ia64-linux-gnuAdhemerval Zanella2024-01-081-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux 6.7 removed ia64 from the official tree [1], following the general principle that a glibc port needs upstream support for the architecture in all the components it depends on (binutils, GCC, and the Linux kernel). Apart from the removal of sysdeps/ia64 and sysdeps/unix/sysv/linux/ia64, there are updates to various comments referencing ia64 for which removal of those references seemed appropriate. The configuration is removed from README and build-many-glibcs.py. The CONTRIBUTED-BY, elf/elf.h, manual/contrib.texi (the porting mention), *.po files, config.guess, and longlong.h are not changed. For Linux it allows cleanup some clone2 support on multiple files. The following bug can be closed as WONTFIX: BZ 22634 [2], BZ 14250 [3], BZ 21634 [4], BZ 10163 [5], BZ 16401 [6], and BZ 11585 [7].

* Remove "Contributed by" linesSiddhesh Poyarekar2021-09-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | We stopped adding "Contributed by" or similar lines in sources in 2012 in favour of git logs and keeping the Contributors section of the glibc manual up to date. Removing these lines makes the license header a bit more consistent across files and also removes the possibility of error in attribution when license blocks or files are copied across since the contributed-by lines don't actually reflect reality in those cases. Move all "Contributed by" and similar lines (Written by, Test by, etc.) into a new file CONTRIBUTED-BY to retain record of these contributions. These contributors are also mentioned in manual/contrib.texi, so we just maintain this additional record as a courtesy to the earlier developers. The following scripts were used to filter a list of files to edit in place and to clean up the CONTRIBUTED-BY file respectively. These were not added to the glibc sources because they're not expected to be of any use in future given that this is a one time task: https://gist.github.com/siddhesh/b5ecac94eabfd72ed2916d6d8157e7dc https://gist.github.com/siddhesh/15ea1f5e435ace9774f485030695ee02 Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* elf/cache.c: Fix resource leaks identified by static analyzersSiddhesh Poyarekar2021-05-181-4/+12
| | | | | | | | | | A coverity run identified a number of resource leaks in cache.c. There are a couple of simple memory leaks where a local allocation is not freed before function return.

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).

* Fix ldconfig segmentation fault with corrupted cache (Bug 18093).Aurelien Jarno2015-03-111-1/+3
| | | | | | | | | | | | | | | | | | | | ldconfig is using an aux-cache to speed up the ld.so.cache update. It is read by mmaping the file to a structure which contains data offsets used as pointers. As they are not checked, it is not hard to get ldconfig to segfault with a corrupted file. This happens for instance if the file is truncated, which is common following a filesystem check following a system crash. This can be reproduced for example by truncating the file to roughly half of it's size. There is already some code in elf/cache.c (load_aux_cache) to check for a corrupted aux cache, but it happens to be broken and not enough. The test (aux_cache->nlibs >= aux_cache_size) compares the number of libs entry with the cache size. It's a non sense, as it basically assumes that each library entry is a 1 byte... Instead this commit computes the theoretical cache size using the headers and compares it to the real size.

* MIPS: IEEE 754-2008 NaN encoding supportMaciej W. Rozycki2013-09-181-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has been a long practice for software using IEEE 754 floating-point arithmetic run on MIPS processors to use an encoding of Not-a-Number (NaN) data different to one used by software run on other processors. And as of IEEE 754-2008 revision [1] this encoding does not follow one recommended in the standard, as specified in section 6.2.1, where it is stated that quiet NaNs should have the first bit (d1) of their significand set to 1 while signalling NaNs should have that bit set to 0, but MIPS software interprets the two bits in the opposite manner. As from revision 3.50 [2][3] the MIPS Architecture provides for processors that support the IEEE 754-2008 preferred NaN encoding format. As the two formats (further referred to as "legacy NaN" and "2008 NaN") are incompatible to each other, tools have to provide support for the two formats to help people avoid using incompatible binary modules. The change is comprised of two functional groups of features, both of which are required for correct support. 1. Dynamic linker support. To enforce the NaN encoding requirement in dynamic linking a new ELF file header flag has been defined. This flag is set for 2008-NaN shared modules and executables and clear for legacy-NaN ones. The dynamic linker silently ignores any incompatible modules it encounters in dependency processing. To avoid unnecessary processing of incompatible modules in the presence of a shared module cache, a set of new cache flags has been defined to mark 2008-NaN modules for the three ABIs supported. Changes to sysdeps/unix/sysv/linux/mips/readelflib.c have been made following an earlier code quality suggestion made here: http://sourceware.org/ml/libc-ports/2009-03/msg00036.html and are therefore a little bit more extensive than the minimum required. Finally a new name has been defined for the dynamic linker so that 2008-NaN and legacy-NaN binaries can coexist on a single system that supports dual-mode operation and that a legacy dynamic linker that does not support verifying the 2008-NaN ELF file header flag is not chosen to interpret a 2008-NaN binary by accident. 2. Floating environment support. IEEE 754-2008 features are controlled in the Floating-Point Control and Status (FCSR) register and updates are needed to floating environment support so that the 2008-NaN flag is set correctly and the kernel default, inferred from the 2008-NaN ELF file header flag at the time an executable is loaded, respected. As the NaN encoding format is a property of GCC code generation that is both a user-selected GCC configuration default and can be overridden with GCC options, code that needs to know what NaN encoding standard it has been configured for checks for the __mips_nan2008 macro that is defined internally by GCC whenever the 2008-NaN mode has been selected. This mode is determined at the glibc configuration time and therefore a few consistency checks have been added to catch cases where compilation flags have been overridden by the user. The 2008 NaN set of features relies on kernel support as the in-kernel floating-point emulator needs to be aware of the NaN encoding used even on hard-float processors and configure the FPU context according to the value of the 2008 NaN ELF file header flag of the executable being started. As at this time work on kernel support is still in progress and the relevant changes have not made their way yet to linux.org master repository. Therefore the minimum version supported has been artificially set to 10.0.0 so that 2008-NaN code is not accidentally run on a Linux kernel that does not suppport it. It is anticipated that the version is adjusted later on to the actual initial linux.org kernel version to support this feature. Legacy NaN encoding support is unaffected, older kernel versions remain supported.

* ARM: Support loading unmarked objects from cache.Carlos O'Donell2013-02-081-0/+4
| | | | | | | | | | | | ARM now supports loading unmarked objects from the dynamic loader cache. Unmarked objects can be used with the hard-float or soft-float ABI. We must support loading unmarked objects during the transition period from a binutils that does not mark objects to one that does mark them with the correct ELF flags.
