From e79137b2fb8bda5e06ee2a618964604831d440cc Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 10 Aug 1999 05:41:26 +0000 Subject: [PATCH] Update. 1999-08-09 Scott Bambrough * elf/elf.h: Added definition of ELFOSABI_ARM. * elf/dl-load.c (_dl_map_object_from_fd): Use VALID_ELF_HEADER, VALID_ELF_OSABI, VALID_ELF_ABIVERSION to decide whether an object's header and ABI values are acceptable. (VALID_ELF_HEADER): New macro; provide default definition. (VALID_ELF_OSABI): New macro; provide default definition. (VALID_ELF_ABIVERSION): New macro; provide default definition. * sysdeps/arm/dl-machine.h Define ARM specific versions of VALID_ELF_HEADER, VALID_ELF_OSABI, VALID_ELF_ABIVERSION. 1999-08-09 Andreas Schwab * inet/tst-ipnode.c (main): Don't compare integer with NULL. 1999-08-09 Thorsten Kukuk * sunrpc/svc_run.c (svc_run): Free my_pollfd. 1999-08-09 Andreas Schwab * sunrpc/svc.c (svc_getreq_poll): Fix argument of xprt_unregister. --- ChangeLog | 24 ++++++++++++++++++++++++ elf/dl-load.c | 16 +++++++++++----- elf/elf.h | 1 + inet/tst-ipnode.c | 2 +- sunrpc/svc.c | 2 +- sunrpc/svc_run.c | 3 +++ sysdeps/arm/dl-machine.h | 8 ++++++++ 7 files changed, 49 insertions(+), 7 deletions(-) diff --git a/ChangeLog b/ChangeLog index 76aa414..7d3e361 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,27 @@ +1999-08-09 Scott Bambrough + + * elf/elf.h: Added definition of ELFOSABI_ARM. + * elf/dl-load.c (_dl_map_object_from_fd): Use VALID_ELF_HEADER, + VALID_ELF_OSABI, VALID_ELF_ABIVERSION to decide whether an + object's header and ABI values are acceptable. + (VALID_ELF_HEADER): New macro;
