2021-02-23assumptions: check C++17 assumption with MSVCfanquake
From my reading of https://docs.microsoft.com/en-us/cpp/build/reference/zc-cplusplus?view=msvc-160 and https://devblogs.microsoft.com/cppblog/msvc-now-correctly-reports-__cplusplus/ if we set the `/Zc:__cplusplus` switch in additional options, MSVC will report the correct value for `__cplusplus`.

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.

While this isn't a supported build configuration, some build systems need to build without going through our autotools steps, so defaulting to something sane may make it easier to build. Specifically, this fixes the inability to build rust-bitcoinconsensus on some non-x86 platforms. It needs to build without our autotools/configure steps to ensure correct compile args are passed from the rust build system to gcc. Converting the args from the rust build system to gcc would be a lot of unmaintainable work.

bitcoin-config.h moved, but the old file is likely to still exist when reconfiguring or switching branches. This would've caused files to not rebuild correctly, and other strange problems. Make the path explicit so that the old one cannot be found. Core libs use config/bitcoin-config.h. Libs (like crypto) which don't want access to bitcoin's headers continue to use -Iconfig and #include bitcoin-config.h.

2014-04-10build: add glibc/libstdc++ back-compat stubsCory Fields
glibc/libstdc++ have added new symbols in later releases. When running a new binary against an older glibc, the run-time linker is unable to resolve the new symbols and the binary refuses to run. This can be fixed by adding our own versions of those functions, so that the build-time linker does not emit undefined symbols for them. This enables our binary releases to work on older Linux distros, while not incurring the downsides of a fully static binary.
