2022-07-29ripple/minitrace: don't impl Copy for SyscallEntryedef
We'd like to be able to have heap-allocated syscall data, which means we can't impl Copy. Change-Id: Ib40dcaf7f99baeaae0dae1153e80deae88d76978

2022-07-29ripple/minitrace: match identifier style in macrosedef
Having macro identifiers match the "real" identifier style makes macro code markedly more readable. Change-Id: Ib675390cc04941ce782c75b2ee686709441081fc

2022-07-28ripple/minitrace: mark file descriptor parametersedef
This doesn't specifically handle * the distinction between borrowed/owned file descriptors (in non-return positions, that only applies to `close`) * "nullable" fd parameters (-1 for not-present) * other sentinel fds, like AT_FDCWD * fd validity in general Change-Id: I00fa68ec94b8f24e28c661d0c007becb37c0a5f3

2022-07-27ripple/minitrace: better errors for invalid syscall argsedef
Change-Id: I26356c9b88c838e3c87e4083ac17f958c7c57bb7
2022-07-27ripple/minitrace: introduce syscall_bitflags!edef
Squeeze the bitflags / SyscallArg impl boilerplate into one macro. Change-Id: I5b5213b6f3ee11bc61b6f8439ceb2510ef6dffec
2022-07-27ripple/minitrace: implement SyscallArg for bitflagsedef

2022-07-27ripple/minitrace: disable dead_code lint on SyscallArgsedef
Every single syscall arg producing a warning is just noisy. Change-Id: I339260886110e2982217ebbf9d29cb1cf91c747c
2022-07-27ripple/minitrace: refactor syscall interpretationV
We separate type-based parsing of syscall arguments from more detailed validation based on multiple parameters or on specific values. The former is implemented with a macro that takes syscall signatures and generates the relevant enum variant and parsing code.

2022-07-27ripple/minitrace: fix newfstatat dirfd handlingedef
Same bug as Ied63822001c8700fc71c89ec16d18036fbc33972, hiding missing behaviour around dirfd. newfstatat(AT_FDCWD, path, …) is used, as is newfstatat(fd, "", …). Change-Id: I03b9dc5118d7a47514abef82c4a577e8362fbb4d
2022-07-08ripple/minitrace: convert openat dirfd correctlyedef
Our conversion always mangled it, *and* our comparison was inverted, so both bugs remained hidden. Change-Id: Ied63822001c8700fc71c89ec16d18036fbc33972
2022-06-19ripple/minitrace: fix syscall ABIV
The fourth argument is passed in r10, not rcx, which is merely clobbered by syscalls. Change-Id: I0c7210c621f6955deccf21348ce6f495424555cc
2022-06-17ripple/minitrace: add set_tid_address, set_robust_list, and getrandomV

2022-02-16ripple/minitrace: use CString::from_vec_with_nul for constructionV

2022-02-08ripple/minitrace: clean up ioctl handlingV
TIOCGWINSZ was mistakenly listed as TCGETS, and parameter destructuring got cleaned up. Change-Id: I8dce783c50d34ab619cf7b05c9b705b5e11bc459

2022-02-07ripple/minitrace: use anyhow::Result unqualifiededef

2021-12-27ripple/minitrace: enforce permitted syscall numbersedef
This doesn't discriminate between muxed syscalls yet, but at least bounds the available syscalls to the ones `cc1 hello.c` invokes. Change-Id: I1965f27746b509b32d5e86510e803038765c11dd
