2023-01-22Fix for CVE-2022-29503.linted
Changed linux thread's stack allocation mmap to use new MAP_FIXED_NOREPLACE flag on kernels >4.17. For older kernels, a check is added to see if requested address matches the address received. If the addresses don't match, an error is returned and thread creation is aborted. Signed-off-by: linted <linted@users.noreply.github.com>
2016-09-26use a single libc and deduplicate threading codeWaldemar Brodkorb
Similar to musl libc a single libc has many benefits and solves some open issues with uClibc-ng. - no pthread_mutex_* weak symbols exported anymore - applications no longer failing to link when either -lrt or -lpthread are missing for dynamic and static linking mode - smaller C library - slightly better runtime performance
2016-05-18remove linuxthreads.new, rename linuxthreads.oldWaldemar Brodkorb
Linuxthreads.new isn't really useful with the existence of NPTL/TLS for well supported architectures. There is no reason to use LT.new for ARM/MIPS or other architectures supporting NPTL/TLS. It is not available for noMMU architectures like Blackfin or FR-V. To simplify the live of the few uClibc-ng developers, LT.new is removed and LT.old is renamed to LT. LINUXTHREADS_OLD -> UCLIBC_HAS_LINUXTHREADS

2009-03-12linuxthreads fixes from Will Newton (will.newton AT gmail.com):Denis Vlasenko
* share Sys V semaphores in order to get appropriate SEM_UNDO semantics. * correct guardaddr in pthread_free() for TLS case * move spinlock unlocking before restart() * When exit was called from a signal handler, the restart from the manager processing the exit request instead restarted the thread in pthread_cond_timedwait. (see http://sources.redhat.com/ml/libc-ports/2006-05/msg00000.html)

2003-08-01Add a new *scanf implementation, includeing the *wscanf functions.Manuel Novoa III
Should be standards compliant and with several optional features, including support for hexadecimal float notation, locale awareness, glibc-like locale-specific digit grouping with the `'' flag, and positional arg support. I tested it pretty well (finding several bugs in glibc's scanf in the process), but it is brand new so be aware. The *wprintf functions now support floating point output. Also, a couple of bugs were squashed. Finally, %a/%A conversions are now implemented. Implement the glibc xlocale interface for thread-specific locale support. Also add the various *_l(args, locale_t loc_arg) funcs. NOTE!!! setlocale() is NOT threadsafe! NOTE!!! The strto{floating point} conversion functions are now locale aware. The also now support hexadecimal floating point notation. Add the wcsto{floating point} conversion functions. Fix a bug in mktime() related to dst. Note that unlike glibc's mktime, uClibc's version always normalizes the struct tm before attempting to determine the correct dst setting if tm_isdst == -1 on entry. Add a stub version of the libintl functions. (untested) Fixed a known memory leak in setlocale() related to the collation data. Add lots of new config options (which Erik agreed to sort out :-), including finally exposing some of the stripped down stdio configs. Be careful with those though, as they haven't been tested in a long time. (temporary) GOTCHAs... The ctype functions are currently incorrect for 8-bit locales. They will be fixed shortly. The ctype functions are now table-based, resulting in larger staticly linked binaries. I'll be adding an option to use the old approach in the stub locale configuration.
2003-02-27Major update for pthreads, based in large part on improvementsEric Andersen
from glibc 2.3. This should make threads much more efficient. -Erik
2003-01-23Just be a bit less different from latest glibc version in commentsEric Andersen
and in the files where variables live.
2003-01-23Per patch from Nathan Field at ghs.com, add a couple of variablesEric Andersen
needed to make gdb happy when debugging threadded apps.
2002-10-29A patch from Arne Jonsson <arne.jonsson@i3micro.com>:Eric Andersen
Attached are the changes we think is necessary in order to use user defined stacksizes for each thread. When testing I forgot to lower the PTHREAD_STACK_MIN to the lowest value used for the stacks, this caused stranged reboots. As said before, we are using uClinux 2.0.38 on a ARM7TDMI.
2002-10-23A patch from Arne Jonsson <arne.jonsson@i3micro.com> to allowEric Andersen
uClibc's libpthread to run on linux 2.0.x kernels which lack poll() and therefore must use select() instead.
2002-02-20Merge in the pthread library. This is the linuxthreads library taken fromEric Andersen
glibc 2.1.3 and ported to work with uClibc by Stefan Soucek and Erik Andersen (me). Stefan has hacked things up such that linuxthreads runs on MMU-less systems (tested only on arm-nommu). Erik cleaned things up and made it work properly as a shared library. -Erik
