debuginfod 1/2: client side 2019-11-22T21:49:21+00:00 Aaron Merey amerey@redhat.com 2019-10-28T17:29:26+00:00 288f6b199a8b1a60d4fb1f54ca7b883cdd5afca2 Introduce the debuginfod/ subdirectory, containing the client for a new debuginfo-over-http service, in shared-library and command-line forms. Two functions in libdwfl make calls into the client library to fetch elf/dwarf files by buildid, as a fallback. Instead of normal dynamic linking (thus pulling in a variety of curl dependencies), the libdwfl hooks use dlopen/dlsym. Server & tests coming in patch 2.

libdw: Introduce libdw_unalloc to stop Dwarf_Abbrev leaks. 2019-11-12T21:33:56+00:00 Mark Wielaard mark@klomp.org 2019-11-10T23:15:55+00:00 287e502815bf133f64afbf47211b11364a0a322f In the case of reading an invalid abbrev or when reading an abbrev concurrently the Dwarf_Abbrev just created might leak because it isn't needed after all. Introduce libdw_unalloc and libdw_typed_unalloc to unallocate such Dwarf_Abbrevs so they don't leak. Signed-off-by: Mark Wielaard <mark@klomp.org>

libdw: Rewrite the memory handler to be more robust. 2019-11-08T16:14:52+00:00 Jonathon Anderson jma14@rice.edu 2019-08-25T15:07:00+00:00 32cd9c4ad5b888da9c4f94a702a02d380b2a745b Pthread's thread-local variables are highly limited, which makes it difficult to use many Dwarfs. This replaces that with a less efficient (or elegant) but more robust method. Signed-off-by: Jonathon Anderson <jma14@rice.edu>

libdw: Don't free uninitialized Dwarf_Abbrev_Hash's of "fake" CUs. 2019-11-02T00:31:47+00:00 Jonathon Anderson jma14@rice.edu 2019-11-01T13:14:05+00:00 09c9e8091c36eff7f1f4220ac12afe66d0322c59 fake_{loc,loclists,addr}_cu are Dwarf_CUs that are created separate from all the others, so their contents are minimal and mostly initialized by a calloc. On dwarf_end however, they are freed through the same code path as all the others, so they call DAH_free like all the others. This changes that so that these three are exempt from DAH and split-DWARF matters, and swaps the calloc for a malloc so Memcheck will catch any others.

Don't use dlopen() for libebl modules 2019-08-29T11:30:30+00:00 Omar Sandoval osandov@fb.com 2019-08-26T17:51:46+00:00 4f937e24dc7ad1820fc7c99a6dd6422657f14666 Currently, architecture-specific code for libebl exists in separate libebl_$ARCH.so libraries which libebl loads with dlopen() at runtime. This makes it impossible to have standalone, statically-linked binaries which use libdwfl if they depend on any architecture-specific functionality. Additionally, when these libraries cannot be found, the failure modes are non-obvious. So, let's get rid of libebl_$arch.so and move it all into libdw.so/libdw.a, which simplifies things considerably. Signed-off-by: Omar Sandoval <osandov@fb.com>
