2020-08-25Return non-zero size for tmpfs statfs(2).Jamie Liu
This does not implement accepting or enforcing any size limit, which will be more complex and has performance implications; it just returns a fixed non-zero size. Updates #1936 PiperOrigin-RevId: 328428588

2020-08-20Consistent precondition formattingMichael Pratt
Our "Preconditions:" blocks are very useful to determine the input invariants, but they are bit inconsistent throughout the codebase, which makes them harder to read (particularly cases with 5+ conditions in a single paragraph). I've reformatted all of the cases to fit in simple rules: 1. Cases with a single condition are placed on a single line. 2. Cases with multiple conditions are placed in a bulleted list. This format has been added to the style guide. I've also mentioned "Postconditions:", though those are much less frequently used, and all uses already match this style. PiperOrigin-RevId: 327687465

2020-07-15fdbased: Vectorized write for packet; relax writev syscall filter.Ting-Yu Wang
Now it calls pkt.Data.ToView() when writing the packet. This may require copying when the packet is large, which puts the worse case in an even worse situation. This sent out in a separate preparation change as it requires syscall filter changes. This change will be followed by the change for the adoption of the new PacketHeader API.

2020-06-10Deleting the maxSendBufferSize from fs/hostBin Lu
When I do high-performance networking, the value of wmem_max is often set very high, specially for 10/25/50 Gigabit NIC. I think maybe this restriction is not suitable. Signed-off-by: Bin Lu <bin.lu@arm.com>

In VFS1, both fs/host and fs/gofer used the same utils for host file mappings. Refactor parts of fsimpl/gofer to create similar utils to share with fsimpl/host (memory accounting code moved to fsutil, page rounding arithmetic moved to usermem). Updates #1476. PiperOrigin-RevId: 312345090
