Updated by Philippe Antoine almost 2 years ago
I wonder if https://github.com/OISF/suricata/pull/8331 will help.
How come gap_size value changes in the stack trace ? like
#25 suricata::filetracker::FileTransferTracker::update (self=0x7fe78d707720, files=0x7fed72b27100, flags=<optimized out>, data=..., gap_size=0) at src/filetracker.rs:307
is_gap = <optimized out>
consumed = 0
#26 0x000056282e4e089f in suricata::smb::smb::SMBState::filetracker_update (self=<optimized out>, direction=<optimized out>, data=..., gap_size=1140876500) at src/smb/files.rs:214
Scenario to reproduce this is have a pcap with a smb2 write, change its length in the SMB2 field to be really big, change the next packets to have a TCP sequence + ack numbers 1G later
Than in parse_tcp_data_ts_gap, let gap = vec![0; new_gap_size as usize];. should allocate big and make it pass through the util file append...
Updated by Philippe Antoine almost 2 years ago
But is there some mechanism to prevent a SMB file transfer over 1G to allocate over 1G in the streaming buffer of the file ?
Updated by Philippe Antoine almost 2 years ago
I have some 2Gbytes pcap that gets Warning: streaming-buffer: StreamingBuffer::Grow() tried to alloc 1084227584 bytes, exceeds limit of 1073741824 [util-streaming-buffer.c:499]
Should we work on this ?
Like why does Suricata need to store this in memory ?
