[PATCH v3 1/4] iphlpapi: Fix ULONG comparisons, most notably for IPv4 addresses.
by Francois Gouget 16 Feb '22

16 Feb '22

The difference between two ULONGs may not fit in an int, causing sorting errors. Signed-off-by: Francois Gouget <fgouget(a)codeweavers.com> --- v2: Introduce DWORD_cmp() to simplify the comparisons. v3: Spelling fix. Resent as one patchset so the tests should succeed on the last part. Note: ipaddrrow_cmp() and ipforward_row_cmp() should do byte-swapping too. This will go in the next patch. The IPv6 address comparisons use memcmp() so the resulting value should fit in an int. My computer has UDP servers listening on 192.* and 0.* but the 192.* entries preceeded the 0.* ones in the UDP table returned by GetUdpTable(). Because of this SnmpExtensionQuery(SNMP_PDU_GETNEXT) found that the last matching UDP entry was lower than the table's first entry and thus returned the first entry instead of the next one. This resulted in an infinite loop in inetmib1:main depending on the exact set of running UDP servers and IPv4 addresses. https://test.winehq.org/data/patterns.html#inetmib1:main --- dlls/iphlpapi/iphlpapi_main.c | 45 +++++++++++++++++------------------ 1 file changed, 22 insertions(+), 23 deletions(-) diff --git a/dlls/iphlpapi/iphlpapi_main.c b/dlls/iphlpapi/iphlpapi_main.c index 53b5006d771..6fe0cbc58f4 100644 --- a/dlls/iphlpapi/iphlpapi_main.c +++ b/dlls/iphlpapi/iphlpapi_main.c @@ -1593,9 +1593,15 @@ DWORD WINAPI GetIfEntry( MIB_IFROW *row ) return err; } +static int DWORD_cmp( DWORD a, DWORD b ) +{ + return a < b ? -1 : a > b ? 1 : 0; /* a subtraction would overflow */ +} + static int ifrow_cmp( const void *a, const void *b ) { - return ((const MIB_IFROW*)a)->dwIndex - ((const MIB_IFROW*)b)->dwIndex; + const MIB_IFROW *rowA = a, *rowB = b; + return DWORD_cmp(rowA->dwIndex, rowB->dwIndex); } /****************************************************************** @@ -1921,7 +1927,8 @@ done: static int ipaddrrow_cmp( const void *a, const void *b ) { - return ((const MIB_IPADDRROW*)a)->dwAddr - ((const MIB_IPADDRROW*)b)->dwAddr; + const MIB_IPADDRROW *rowA = a, *rowB = b; + return DWORD_cmp(rowA->dwAddr, rowB->dwAddr); } /****************************************************************** @@ -2026,14 +2033,11 @@ DWORD WINAPI AllocateAndGetIpAddrTableFromStack( MIB_IPADDRTABLE **table, BOOL s static int ipforward_row_cmp( const void *a, const void *b ) { - const MIB_IPFORWARDROW *rowA = a; - const MIB_IPFORWARDROW *rowB = b; - int ret; - - if ((ret = rowA->dwForwardDest - rowB->dwForwardDest) != 0) return ret; - if ((ret = rowA->dwForwardProto - rowB->dwForwardProto) != 0) return ret; - if ((ret = rowA->dwForwardPolicy - rowB->dwForwardPolicy) != 0) return ret; - return rowA->dwForwardNextHop - rowB->dwForwardNextHop; + const MIB_IPFORWARDROW *rowA = a, *rowB = b; + return DWORD_cmp(rowA->dwForwardDest, rowB->dwForwardDest) || + DWORD_cmp(rowA->dwForwardProto, rowB->dwForwardProto) || + DWORD_cmp(rowA->dwForwardPolicy, rowB->dwForwardPolicy) || + DWORD_cmp(rowA->dwForwardNextHop, rowB->dwForwardNextHop); } /****************************************************************** @@ -2277,10 +2281,8 @@ err: static int ipnetrow_cmp( const void *a, const void *b ) { - const MIB_IPNETROW *row_a = a; - const MIB_IPNETROW *row_b = b; - - return RtlUlongByteSwap( row_a->dwAddr ) - RtlUlongByteSwap( row_b->dwAddr ); + const MIB_IPNETROW *rowA = a, *rowB = b; + return DWORD_cmp(RtlUlongByteSwap( rowA->dwAddr ), RtlUlongByteSwap( rowB->dwAddr )); } /****************************************************************** @@ -3043,13 +3045,12 @@ static void tcp_row_fill( void *table, DWORD num, ULONG family, ULONG table_clas static int tcp_row_cmp( const void *a, const void *b ) { - const MIB_TCPROW *rowA = a; - const MIB_TCPROW *rowB = b; + const MIB_TCPROW *rowA = a, *rowB = b; int ret; - if ((ret = RtlUlongByteSwap( rowA->dwLocalAddr ) - RtlUlongByteSwap( rowB->dwLocalAddr )) != 0) return ret; + if ((ret = DWORD_cmp(RtlUshortByteSwap( rowA->dwLocalAddr ), RtlUshortByteSwap( rowB->dwLocalAddr ))) != 0) return ret; if ((ret = RtlUshortByteSwap( rowA->dwLocalPort ) - RtlUshortByteSwap( rowB->dwLocalPort )) != 0) return ret; - if ((ret = RtlUlongByteSwap( rowA->dwRemoteAddr ) - RtlUlongByteSwap( rowB->dwRemoteAddr )) != 0) return ret; + if ((ret = DWORD_cmp(RtlUshortByteSwap( rowA->dwRemoteAddr ), RtlUshortByteSwap( rowB->dwRemoteAddr ))) != 0) return ret; return RtlUshortByteSwap( rowA->dwRemotePort ) - RtlUshortByteSwap( rowB->dwRemotePort ); } @@ -3432,12 +3433,10 @@ static void udp_row_fill( void *table, DWORD num, ULONG family, ULONG table_clas static int udp_row_cmp( const void *a, const void *b ) { - const MIB_UDPROW *rowA = a; - const MIB_UDPROW *rowB = b; - int ret; + const MIB_UDPROW *rowA = a, *rowB = b; - if ((ret = RtlUlongByteSwap( rowA->dwLocalAddr ) - RtlUlongByteSwap( rowB->dwLocalAddr )) != 0) return ret; - return RtlUshortByteSwap( rowA->dwLocalPort ) - RtlUshortByteSwap( rowB->dwLocalPort ); + return DWORD_cmp(RtlUlongByteSwap( rowA->dwLocalAddr), RtlUlongByteSwap( rowB->dwLocalAddr )) || + RtlUshortByteSwap( rowA->dwLocalPort ) - RtlUshortByteSwap( rowB->dwLocalPort ); } static int udp6_row_cmp( const void *a, const void *b ) -- 2.30.2
