Ok, I will modify the code ,and send out the new patch again -----Original Message----- From: Carsey, Jaben [mailto:jaben.car...@intel.com] Sent: Tuesday, June 30, 2015 10:51 PM To: edk2-devel@lists.sourceforge.net Subject: Re: [edk2] [patch 2/2] NetworkPkg:Replace unsafe string functions.
You have the number 128 added in lots of places. Where is this number from? Should you use a #define or a PCD or something? If the string was made longer, this would be painful to update so many locations. Inline comments also. >-----Original Message----- >From: Zhang Lubo [mailto:lubo.zh...@intel.com] >Sent: Tuesday, June 30, 2015 1:26 AM >To: edk2-devel@lists.sourceforge.net >Subject: [edk2] [patch 2/2] NetworkPkg:Replace unsafe string functions. > >Replace unsafe string functions with new added safe string functions. > >Contributed-under: TianoCore Contribution Agreement 1.0 >Signed-off-by: Zhang Lubo <lubo.zh...@intel.com> >--- > NetworkPkg/Application/IfConfig6/IfConfig6.c | 6 ++-- > NetworkPkg/Application/IpsecConfig/Indexer.c | 2 +- > .../Application/IpsecConfig/PolicyEntryOperation.c | 4 +-- > NetworkPkg/IScsiDxe/IScsiConfig.c | 2 +- > NetworkPkg/IScsiDxe/IScsiDhcp.c | 2 +- > NetworkPkg/IScsiDxe/IScsiDhcp6.c | 2 +- > NetworkPkg/IScsiDxe/IScsiExtScsiPassThru.c | 2 +- > NetworkPkg/Mtftp6Dxe/Mtftp6Support.c | 13 +++++---- > NetworkPkg/UefiPxeBcDxe/PxeBcMtftp.c | 32 ++++++++++++---------- > NetworkPkg/UefiPxeBcDxe/PxeBcSupport.c | 6 ++-- > NetworkPkg/UefiPxeBcDxe/PxeBcSupport.h | 6 ++-- > 11 files changed, 44 insertions(+), 33 deletions(-) > >diff --git a/NetworkPkg/Application/IfConfig6/IfConfig6.c >b/NetworkPkg/Application/IfConfig6/IfConfig6.c >index 9e228ca..ded3df5 100644 >--- a/NetworkPkg/Application/IfConfig6/IfConfig6.c >+++ b/NetworkPkg/Application/IfConfig6/IfConfig6.c >@@ -134,11 +134,11 @@ SplitStrToList ( > // > // Copy the CONST string to a local copy. > // > Str = (CHAR16 *) AllocateZeroPool (StrSize (String));
