Simplify the abilist format The new format lists the version on each line, as in: VERSION SYMBOL TYPE [VALUE] This makes it easier to process the files with line-oriented tools. The abilist files were converted with this awk script: /^[^ ]/ { version = $1 } /^ / { print version, substr($0, 2) } And sorted under the "C" locale with sort. 2015-10-29 14:33:54 +00:00			`GLIBC_2.17 __libc_stack_end D 0x8`

Fix glibc 2.34 ABI omission (missing GLIBC_2.34 in dynamic loader) The glibc 2.34 release really should have added a GLIBC_2.34 symbol to the dynamic loader. With it, we could move functions such as dlopen or pthread_key_create that work on process-global state into the dynamic loader (once we have fixed a longstanding issue with static linking). Without the GLIBC_2.34 symbol, yet another new symbol version would be needed because old glibc will fail to load binaries due to the missing symbol version in ld.so that newly linked programs will require.

nptl: Add public rseq symbols and <sys/rseq.h> The relationship between the thread pointer and the rseq area is made explicit. The constant offset can be used by JIT compilers to optimize rseq access (e.g., for really fast sched_getcpu). Extensibility is provided through __rseq_size and __rseq_flags. (In the future, the kernel could request a different rseq size via the auxiliary vector.)
