1.1.9 release notes
|
||||
|
||||
new features:
|
||||
- ability to protect libc code itself with stack protector
|
||||
- sigsetjmp now restores signal mask after restoring context, not before
|
||||
- thread-local dlerror status/messages
|
||||
- dlerror messages are no longer truncated
|
||||
- diagnostics for constraint violations with ctype.h macros
|
||||
|
||||
optimizations:
|
||||
- reduce cost of PIC on archs where PLT calls need a fixed GOT register
|
||||
- spin locks no longer constantly invalidate cache lines while spinning
|
||||
- code size reduction in static-linked TLS init
|
||||
|
||||
bugs fixed:
|
||||
- failure to process robust mutexes on detached-thread exit
|
||||
- possible memory corruption due to robust mutex list on detached-thread exit
|
||||
- crash on memory exhaustion in getgr* internals
|
||||
- misaligned memory accesses in static binaries with low-alignment TLS blocks
|
||||
- multiple cases of wrongful path search continuation after transient failure
|
||||
- small memory leak on failure of dlopen with RPATH $ORIGIN
|
||||
- several small math bugs related to exception flags with non-finite args
|
||||
- mmap leak in sem_open failure path for link call
|
||||
- duplocale clobbered new locale struct with memcpy of old
|
||||
- futimes crashed with null timeval argument
|
||||
|
||||
arch-specific bugs fixed:
|
||||
- stack protector spuriously aborted after forking on x32
|
||||
- stack protector spuriously aborted with flockfile on powerpc
|
||||
- theoretically-possible clobbering of syscall return value on mips
|
||||
- random thread-pointer setup failure on sh (uninitialized return value)
|
||||
- possible crash in dlsym on sh due to incorrectly-computed branch target
|
||||
- broken fesetenv(FE_DFL_ENV) on mips
|
||||
- dynamic linker name for sh ignored fpu/nofpu and endianness
|
||||
- various minor aarch64 bugs
|
||||
- dangling pointers in x32 syscall timespec fixup code
