[Samba] 3.6.10 file handle leak under ancient 32-bit kernel

[starlight.2013q1 at binnacle.cx]

Looking at the good system:


open("log", O_RDONLY|O_DIRECTORY)       = 28
fstat(28, {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
fstat(28, {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
fcntl(28, F_GETFL)                      = 0x18000 (flags O_RDONLY|O_LARGEFILE|O_DIRECTORY)
fcntl(28, F_SETFD, FD_CLOEXEC)          = 0
getdents(28, /* 184 entries */, 32768)  = 5880
getdents(28, /* 0 entries */, 32768)    = 0
close(28)                               = 0

open(".", O_RDONLY|O_DIRECTORY)         = 28
fstat(28, {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
close(28)                               = 0

open("log", O_RDONLY|O_DIRECTORY)       = 28
fstat(28, {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
fstat(28, {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
fcntl(28, F_GETFL)                      = 0x18000 (flags O_RDONLY|O_LARGEFILE|O_DIRECTORY)
fcntl(28, F_SETFD, FD_CLOEXEC)          = 0
getdents(28, /* 184 entries */, 32768)  = 5880
getdents(28, /* 0 entries */, 32768)    = 0
close(28)                               = 0


Where on the bad system:

open("log", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY) = 509
fstat64(509, {st_mode=S_IFDIR|0751, st_size=4096, ...}) = 0
fcntl64(509, F_SETFD, FD_CLOEXEC)       = 0
getdents64(509, /* 129 entries */, 4096) = 4072
getdents64(509, /* 46 entries */, 4096) = 1488
getdents64(509, /* 0 entries */, 4096)  = 0
close(509)                              = 0

open(".", O_RDONLY|O_LARGEFILE|O_DIRECTORY) = 509
fstat64(509, {st_mode=S_IFDIR|0751, st_size=4096, ...}) = 0
close(509)                              = 0

open("log", O_RDONLY|O_LARGEFILE|O_DIRECTORY) = 509
fstat64(509, {st_mode=S_IFDIR|0751, st_size=4096, ...}) = 0
