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
2022-07-29ripple/minitrace: pluralise newfstatat flags parameteredef

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: remove GRND_ prefix from GrndFlagsedef

2022-07-27ripple/minitrace: mmap fd is an i32, not u64edef
Change-Id: I092d4f47231d560a0c4ac023e63051def34c2c92
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. 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
2022-06-19Make rustfmt.toml globaledef

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
With this, minitrace has all the syscalls needed to run cc1. Change-Id: Iaeef58769f69d64e192af2270eb520e891daec94
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
A little more explicit, and a bit more readable. Change-Id: Id462c46236e1de547aabd36409260bd1c99f6f88
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

2022-05-05ripple/fossil/mount: terminate out-of-bounds Node::find earlyedef
Node::find would walk the tree all the way down and to the right if given an out of bounds index. This doesn't affect the return value (None), but it does waste some cycles walking down all the way to the deepest rightmost leaf. Change-Id: Ic2f72aa96291a25819fc6c3c2f060fe0182a7663
