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: introduce syscall_bitflags!edef
Squeeze the bitflags / SyscallArg impl boilerplate into one macro. Change-Id: I5b5213b6f3ee11bc61b6f8439ceb2510ef6dffec

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. Co-authored-by: edef <edef@unfathomable.blue> Change-Id: I7e334d3e128e7b1461bfd6fae7c8ec5dd6ada0a8
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

2022-06-19ripple/fossil: box the bao decoderedef
Shuffling 3k around on the stack doesn't make anyone happy. Change-Id: I444fc22267380d9b99ca63ca148b9a9e85238b5a
2022-06-17ripple/minitrace: add set_tid_address, set_robust_list, and getrandomV

2022-06-13ripple/fossil: use std::os::unix::preludeedef
We were accidentally grabbing things from the prelude module already, and this is the cleaner fix. Change-Id: I2c6b669164df11f467eae495d109e096eb267b59
2022-06-12ripple/fossil/chunker: use hex_literal rather than hex escapesedef

2022-06-12ripple/website: add SPDX annotationsedef
We haven't picked a license for our web content yet, so this is LicenseRef-NONE for now. Change-Id: Iabfc35860cb8ad0025624161214b1cbb6574e0c5
2022-06-12ripple/shell.nix: provide a wrapper for SUID fusermount(1)edef
fusermount(1) gets shadowed by pkgs.fuse, but we actually need the SUID-root one in the system PATH. This adds a wrapper script that hunts down a SUID-root binary from PATH. Change-Id: Icc5c6789d7b74bf8f6e3c50529333eb6b894527f
2022-05-10ripple/fossil: permit importing trees from git reposedef
