2021-08-20[op] Prevent file leak in MultiGetAttr's error path.Ayush Ranjan
The old implementation was mostly correct but error prone - making way for the issue in question here. In its error path, it would leak the intermediate file being walked. Each return/break needed explicit cleanup. This change implements a more clean way to cleaning up intermediate directories. If the code were to evolve to be more complex, it would still work.

2021-08-20Fix lock ordering violation introduced in cl/347704347.Nicolas Lacasse
We cannot hold mm.aioManager.mu while calling MUnmap, because MUnmap attempts to aquire mm.mappingMu. This violates the lock order as documented in mm/mm.go. PiperOrigin-RevId: 392102472

2021-08-20Fix instructions refer to `tools/go_mod.sh`Daniel Dao
`tools/go_mod.sh` is not in the repo. In order to update the WORKSPACE dependencies, we can use the same gazelle command in BUILD file. Also changed `go mod get` to `go get`, the former does not exist anymore. Signed-off-by: Daniel Dao <dqminh89@gmail.com>

Add an LRU cache to cache verity dentries when ref count drop to 0. This way we don't need to hash and verify the previous opened files or directories each time. PiperOrigin-RevId: 391880157

2021-08-19Use MM-mapped I/O instead of buffered copies in gofer.specialFileFD.Jamie Liu
The rationale given for using buffered copies is still valid, but it's unclear whether holding MM locks or allocating buffers is better in practice, and the former is at least consistent with gofer.regularFileFD (and VFS1), making performance easier to reason about. PiperOrigin-RevId: 391877913

2021-08-19Add loopback interface as an ethernet-based deviceGhanan Gowripalan
...to match Linux behaviour. We can see evidence of Linux representing loopback as an ethernet-based device below: ``` # EUI-48 based MAC addresses. $ ip link show lo 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 # tcpdump showing ethernet frames when sniffing loopback and logging the # link-type as EN10MB (Ethernet). $ sudo tcpdump -i lo -e -c 2 -n tcpdump: verbose output suppressed, use -v[v]... for full protocol decode listening on lo, link-type EN10MB (Ethernet), snapshot length 262144 bytes 03:09:05.002034 00:00:00:00:00:00 > 00:00:00:00:00:00, ethertype IPv4 (0x0800), length 66: 127.0.0.1.9557 > 127.0.0.1.36828: Flags [.], ack 3562800815, win 15342, options [nop,nop,TS val 843174495 ecr 843159493], length 0 03:09:05.002094 00:00:00:00:00:00 > 00:00:00:00:00:00, ethertype IPv4 (0x0800), length 66: 127.0.0.1.36828 > 127.0.0.1.9557: Flags [.], ack 1, win 6160, options [nop,nop,TS val 843174496 ecr 843159493], length 0 2 packets captured 116 packets received by filter 0 packets dropped by kernel ``` Wireshark shows a similar result as the tcpdump example above.

2021-08-18Declare default outputs from nogo_stdlibMichael Pratt
nogo_stdlib propogate facts and findings to downstream nogo_aspects via NogoStdlibInfo. This all works fine except one case: directly building a nogo_stdlib. e.g., bazel build //tools/nogo:stdlib. In this case, nothing is requesting the NogoStdlibInfo, and thus the target has nothing to do. This can be rather confusing when trying to debug failures in :stdlib, as building :stdlib does nothing. Fix this by declaring the facts and findings as default outputs from nogo_stdlib. Now direct bazel build will request these outputs and actually trigger the analysis. Standard aspect builds are unaffected. PiperOrigin-RevId: 391580126

2021-08-17[op] Deflake SNMP Metric proc_net tests.Ayush Ranjan
Earlier the tests were checking for equality of system-wide metrics before and after some network related operations. That is inherently racy for native tests because depending on the testing infrastructure, multiple tests might run parallely hence trampling over each other's metrics. Tests should only compare metrics that are increasing in nature. The comparison should not be a hard comparison, instead a less-than/greater-than relation test. I have changed the checks and also removed tests for tcpCurrEstab metric which has "SYNTAX Gauge" and hence can not be tested reliably. PiperOrigin-RevId: 391460081

2021-08-17Implement control operations on msgqueue.Zyad A. Ali
For IPCInfo, update value of MSGSEG constant in abi to avoid overflow in MsgInfo.MsgSeg. MSGSEG was originaly simplified in abi, and is unused (by us and within the kernel), so updating it is okay. Updates #135
