Description Flags
patch to perform speculative scan forward on * match none

Description Martin Poole 2007-06-19 15:11:14 UTC 
Description of problem:

The wildcarding code misses trivially valid cases

  ls *1

will match

  A1
  b9087654321

but will fail against

  a11

Version-Release number of selected component (if applicable):

vsftpd-2.0.1-5.EL4.5

How reproducible:

always

Steps to Reproduce:
1. create files on server  A1 A21 A11
2. ftp in and ls *1
3.
  
Actual results:

ftp> ls *1
 227 Entering Passive Mode (10,1,2,3,61,93)
 150 Here comes the directory listing.
 -rw-rw-r-- 1 500   500   0 Jun 11 00:30 A1
 -rw-r--r-- 1 0   0   0 Jun 12 01:55 A21

Expected results:

ftp> ls
 227 Entering Passive Mode (10,1,2,3,227,184)
 150 Here comes the directory listing.
 -rw-rw-r-- 1 500   500   0 Jun 11 00:30 A1
 -rw-rw-r-- 1 500   500   0 Jun 11 00:35 A11
 -rw-r--r-- 1 0   0   0 Jun 12 01:55 A21


Additional info:

The problem is due to the fact the match code is not greedy enough. Having found
a match it needs to speculatively scan for further matches without a permanent
failure.
