perf genelf: Set ELF program header addresses properly

2024-01-25T23:35:52+00:00

[ Upstream commit 1af478903fc48c1409a8dd6b698383b62387adf1 ] The text section starts after the ELF headers so PHDR.p_vaddr and others should have the correct addresses.

perf genelf: Fix error code in jit_write_elf()

2022-10-04T11:55:22+00:00

The error code is set to -1 at the beginning of jit_write_elf(), but it is assigned by jit_add_eh_frame_info() in the middle, hence the following error can only return the error code of jit_add_eh_frame_info(). Reset the error code to the default value after being assigned by jit_add_eh_frame_info().

perf jit: Include program header in ELF files

The missing header makes it hard for programs like elfutils to open these files.

perf genelf: Switch deprecated openssl MD5_* functions to new EVP API

genelf: Use HAVE_LIBCRYPTO_SUPPORT, not the never defined HAVE_LIBCRYPTO

2022-08-02T19:32:28+00:00

When genelf was introduced it tested for HAVE_LIBCRYPTO not HAVE_LIBCRYPTO_SUPPORT, which is the define the feature test for openssl defines, fix it. This also adds disables the deprecation warning, someone has to fix this to build with openssl 3.0 before the warning becomes a hard error.

perf tools: Remove perf.h from source files not needing it

2019-08-29T20:38:32+00:00

With the movement of lots of stuff out of perf.h to other headers we ended up not needing it in lots of places, remove it from those places.

And remove unneeded include directives from perf-sys.h to prune the header dependency tree. Fixup the fallout in places where definitions were being used without the needed include directives that were being satisfied because they were in perf-sys.h.
