2024-03-01netbase: refactor CreateSock() to accept sa_family_tMatthew Zipkin
Also implement CService::GetSAFamily() to provide sa_family_t
2024-02-28serialization: use internal endian conversion functionsCory Fields
These replace our platform-specific mess in favor of c++20 endian detection via std::endian and internal byteswap functions when necessary. They no longer rely on autoconf detection.
2024-02-28serialization: detect byteswap builtins without autoconf testsCory Fields
Rather than a complicated set of tests to decide which bswap functions to use, always prefer the compiler built-ins when available. These builtins and fallbacks can all be removed once we're using c++23, which adds std::byteswap.

2023-10-04Remove __cplusplus from compat/assumptions.hMarcoFalke
It is unclear what the goal of this check is, given that the value may need to be set lower for the mimimum supported version of compilers that forgot to bump the value, see https://github.com/bitcoin/bitcoin/pull/28349#issuecomment-1745143612 . The minimum supported compiler versions are already documented in doc/dependencies.md and using an older compiler will already result in a compile failure, so this check can be removed as redundant. Especially given that it is only included in one file, where iwyu suggests to remove it.

2022-05-28compat: remove glibcxx sanity checksfanquake
These checks were added in #4339, (see also #4081), to test our back-compat stubs, however, those stubs no-longer exist (#22930), meaning that these checks are now just testing some specific standard library behaviour, without a particular rationale, or reason, compared to any other standard library functions we use. There has also been some discussion about the sanity checks in the context of the libbitcoinkernel refactoring, see https://github.com/bitcoin/bitcoin/pull/25065#discussion_r880668218. Removing the checks removes the need to worry about atleast the glibcxx checks. Also remove the list of check from the doc in init.h, because it is incomplete, and anyone who wants to know what checks are included can look at the function.
2022-04-20refactor: fix includes in src/compatfanquake
Add missing includes. Swap C headers for their C++ counterparts. Remove pointless / unmaintainable include comments. This is even more the case when we are actually using IWYU, as if anyone wants to see the comments they can just get IWYU to generate them.

2021-03-10compat: remove memcpy -> memmove backwards compatibility aliasfanquake
In glib 2.13 memcpy was changed such that the way it copied bytes was reversed. This caused all sorts of issues for existing software, which depended on the existing behavior (when they should have been using memmove). See: https://sourceware.org/bugzilla/show_bug.cgi?id=12518 https://bugzilla.redhat.com/show_bug.cgi?id=638477 Now that we require glibc 2.17+ (#17538), we should be well clear of having to maintain our memcpy -> memmove aliasing, which was introduced in #4339.

2020-05-07test: remove glibc fdelt sanity checkfanquake
As is, this sanity check doesn't seem to be testing fdelt_chk, because passing a value of "0" to FD_SET wont cause the compiler to insert any calls to fdelt_chk(). The documentation is a little misleading. If we actually triggered fdelt_chk at runtime, bitcoind would abort. I think this check would be better replaced (if possible) by additional checks in security-check.py. The compiler may insert a call to fdelt_warn() (aliased with fdelt_chk in glibc) at compile time if it can determine that an invalid value is being passed to FD_SET. These checks are essentially; value < 0 or value >= FD_SETSIZE along with a check for wether the value is a compile time constant. If the compiler can determine an invalid value is being passed, a call to fdelt_warn will be inserted. Passing 0 should never cause a call to be inserted. You can check this after compiling: ```bash objdump -dC bitcoind | grep sanity_fdelt ... 0000000000399d20 <sanity_test_fdelt()>: 399d20: 48 81 ec 98 00 00 00 sub $0x98,%rsp 399d27: b9 10 00 00 00 mov $0x10,%ecx 399d2c: 64 48 8b 04 25 28 00 mov %fs:0x28,%rax 399d33: 00 00 399d35: 48 89 84 24 88 00 00 mov %rax,0x88(%rsp) 399d3c: 00 399d3d: 31 c0 xor %eax,%eax 399d3f: 48 89 e7 mov %rsp,%rdi 399d42: fc cld 399d43: f3 48 ab rep stos %rax,%es:(%rdi) 399d46: 48 8b 84 24 88 00 00 mov 0x88(%rsp),%rax 399d4d: 00 399d4e: 64 48 33 04 25 28 00 xor %fs:0x28,%rax 399d55: 00 00 399d57: 75 0d jne 399d66 <sanity_test_fdelt()+0x46> 399d59: b8 01 00 00 00 mov $0x1,%eax 399d5e: 48 81 c4 98 00 00 00 add $0x98,%rsp 399d65: c3 retq 399d66: e8 85 df c8 ff callq 27cf0 <__stack_chk_fail@plt> 399d6b: 0f 1f 44 00 00 nopl 0x0(%rax,%rax,1) ``` To test, you could modify this test to pass -1 to FD_SET, and check that a call to fdelt_warn() is inserted, and that running bitcoind fails. i.e: ```bash 0000000000399d20 <sanity_test_fdelt()>: 399d20: 48 81 ec 98 00 00 00 sub $0x98,%rsp 399d27: b9 10 00 00 00 mov $0x10,%ecx 399d2c: 64 48 8b 04 25 28 00 mov %fs:0x28,%rax 399d33: 00 00 399d35: 48 89 84 24 88 00 00 mov %rax,0x88(%rsp) 399d3c: 00 399d3d: 31 c0 xor %eax,%eax 399d3f: 48 89 e7 mov %rsp,%rdi 399d42: fc cld 399d43: f3 48 ab rep stos %rax,%es:(%rdi) 399d46: 48 c7 c7 ff ff ff ff mov $0xffffffffffffffff,%rdi 399d4d: e8 3e ff ff ff callq 399c90 <__fdelt_warn> 399d52: 0f b6 04 24 movzbl (%rsp),%eax 399d56: 83 e0 01 and $0x1,%eax 399d59: 48 8b 94 24 88 00 00 mov 0x88(%rsp),%rdx 399d60: 00 399d61: 64 48 33 14 25 28 00 xor %fs:0x28,%rdx 399d68: 00 00 399d6a: 75 08 jne 399d74 <sanity_test_fdelt()+0x54> 399d6c: 48 81 c4 98 00 00 00 add $0x98,%rsp 399d73: c3 retq 399d74: e8 77 df c8 ff callq 27cf0 <__stack_chk_fail@plt> 399d79: 0f 1f 80 00 00 00 00 nopl 0x0(%rax) ``` ```bash ./src/bitcoind *** buffer overflow detected ***: src/bitcoind terminated Aborted ```
2020-05-07build: remove fdelt_chk backwards compatibility codefanquake
Now that we require glibc 2.17 or later, we no longer need to check for different return types in fdelt_chk. It was changed from unsigned long int to long int in glibc 2.16 . See this commit: https://sourceware.org/git/?p=glibc.git;a=commit;h=ceb9e56b3d1f8c1922e0526c2e841373843460e2 and related issue: https://sourceware.org/bugzilla/show_bug.cgi?id=14210.
