linux/bits.h: fix compilation error with GENMASK

2021-06-03T07:00:45+00:00

[ Upstream commit f747e6667ebb2ffb8133486c9cd19800d72b0d98 ] GENMASK() has an input check which uses __builtin_choose_expr() to enable a compile time sanity check of its inputs if they are known at compile time. However, it turns out that __builtin_constant_p() does not always return a compile time constant [0]. It was thought this problem was fixed with gcc 4.9 [1], but apparently this is not the case [2]. Switch to use __is_constexpr() instead which always returns a compile time constant, regardless of its inputs.

ia64: tools: remove inclusion of ia64-specific version of errno.h header

2021-04-21T11:00:57+00:00

commit 17786fea414393813b56e33a1a01b2dfa03c0915 upstream. There is no longer an ia64-specific version of the errno.h header below arch/ia64/include/uapi/asm/, so trying to build tools/bpf fails with: CC /usr/src/linux/tools/bpf/bpftool/btf_dumper.o In file included from /usr/src/linux/tools/include/linux/err.h:8, from btf_dumper.c:11: /usr/src/linux/tools/include/uapi/asm/errno.h:13:10: fatal error: ../../../arch/ia64/include/uapi/asm/errno.h: No such file or directory 13 | #include "../../../arch/ia64/include/uapi/asm/errno.h" | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated. Thus, just remove the inclusion of the ia64-specific errno.h so that the build will use the generic errno.h header on this target which was used there anyway as the ia64-specific errno.h was just a wrapper for the generic header.

static_call: Allow module use without exposing static_call_key

2021-03-30T12:31:53+00:00

[ Upstream commit 73f44fe19d359635a607e8e8daa0da4001c1cfc2 ] When exporting static_call_key; with EXPORT_STATIC_CALL*(), the module can use static_call_update() to change the function called. This is not desirable in general. Not exporting static_call_key however also disallows usage of static_call(), since objtool needs the key to construct the static_call_site. Solve this by allowing objtool to create the static_call_site using the trampoline address when it builds a module and cannot find the static_call_key symbol. The module loader will then try and map the trampole back to a key before it constructs the normal sites list. Doing this requires a trampoline -> key associsation, so add another magic section that keeps those.

bpf: Fix enum names for bpf_this_cpu_ptr() and bpf_per_cpu_ptr() helpers

2020-12-11T22:19:07+00:00

Remove bpf_ prefix, which causes these helpers to be reported in verifier dump as bpf_bpf_this_cpu_ptr() and bpf_bpf_per_cpu_ptr(), respectively.
